Aqua C Micro Bubbles 5/17/08
Didn't see an answer for my question in the faqs. If
its in there, I’m sorry!
<No problem, it is greatly appreciated that you looked first!>
I just bought an AquaC Remora with the Maxi jet 1200.
<Good setup.>
I CAN NOT get rid of the micro bubbles. I’m not sure if the skimmate cup is too high and its allowing bubbles past, or what.
I would appreciate any opinions!
Thanks!
<Everything sounds normal. As per Aqua C’s directions, the skimmer will put out some micro bubbles while the skimmer is “breaking in”. This has been my experience too. Give it time, they will disappear. A link to Aqua C’s instructions below. Welcome, Scott V.>

Re: Aqua C Micro Bubbles 5/17/08
Thank you very much!
<Welcome very much!>
It has already been a week, so hopefully it will end soon!
<It will, with time. I find one week to be a bit conservative. Usually two or even a few days more.>
This site is fantastic. You guys are all such a great help!
<Thank you!>
Thanks again!
<Welcome, happy reefing, Scott V.>

Skimmer Upgrade? 5/10/08 I currently have a 125 gallon reef tank. The water currently flows downstairs into an Aqua C EV150 skimmer and then into a 58 gallon refugium filled with live sand 6 inches deep and it is full of Chaeto algae. The skimmer is in an acrylic box inside of the 58 gallon tank and water flows through this first, and then through the Chaeto. It then flows down into a sump (28 gallon trash can) and it is then pumped it back to the main tank with a mag 18. Circulation is provided by a Sequence Dart pump on a closed loop. <Sounds nice!> The tank has been set up for about a year and I have a problem with some course wire like algae but otherwise it looks great and the corals are growing like crazy. The tank has 6 Green Chromis, a BlueBand Goby, A 12 year old Clown fish, <Wow!> and a 8 year old Yellow Tang. Lighting consists of 3 175 watt 10,000k halides with 2 20 watt Actinics. I change 16 gallons of water weekly, and top off with Kalkwasser. I converted 2 smaller tanks into this larger one last spring and love it but want the extra volume and security of a larger sump. <Larger never hurts with sumps.> I am upgrading the size of the sump to 75 gallons and was wondering if the additional volume would call for a larger skimmer? Since the bioload is the same I would think that it would not require additional skimming. <Your DOC’s will be diluted a bit more, the skimmer sizing has more to do with the volume of water it can process more than anything. A larger tank does not require a larger skimmer to functionally skim what passes through, it requires a larger skimmer to have the ability to process enough water to accommodate the volume in the tank. But, all things considered you do have a fine skimmer for your system.> I figure the total volume of water in the system will be around 180 to 200 gallons. <Nice.> My thoughts are that as long as the bio-load doesn't change then the skimmer should not have to. The Below is a picture of one half of the tank. <Nice tank.> Thanks, Aaron <Welcome, have fun.>

<<nice! -Sara M.>>

Skimmer Upgrade? 5/10/08 Thanks for your advice. <Welcome.> The reef tank is doing great and Wet Web Media made it all happen. <Thank you, I will pass this around!> I spent days reading the articles and FAQ here prior to setting it up. I was a little concerned about the Blueband Goby since there are articles on here about them not eating well in captivity but he eats from my hand and seems to be thriving. <Great!> I tend to keep my fish around a long time and wanted the same for him. Keep up the good work guys. Aaron <Will do, thank you, Scott V.>

Remora C Pro Skimming Wet, Very Wet – 04/28/08 Hello WWM, <<Hiya Kim...Eric here>> I recently purchased a Remora C Pro w/ a Rio 1400 for my 120 gallon tank. <<Good skimmer and great people (Jason and Steve) and service>> I am not using any other pump parts, only vinyl tubing snap-lock hose clamps to connect the pump to the skimmer. <<Okay>> My tank is healthy and I perform 30% bi-monthly consistent water changes consistently. <<Excellent>> This tank is 1.5 yrs and has gone skimmerless since inception. <<I see>> I upgraded form a 55 that was also skimmerless for 5 yrs. I hooked up the skimmer, raised the cup to its highest position and screwed the injector screw in as far as it will go. Here is the problem, I was pulling soooo much water out, I had to make 20 gallons of saltwater to replenish the amount that was being pulled out. <<Hmm…certainly not desired (or typical) performance>> The skimmate was clear with just the slightest ting of yellow. <<Indeed…something amiss here>> I will need to mix another 20 gallons to continue skimming. <<I would remove the skimmer for the moment, until the issue can be resolved>> I posted on several forums with very little help, I Googled and did not find any similar experiences. <<This last is a good sign [grin]. As stated, this is not typical performance of this product>> I need help. <<Well Kim, I can only guess but if you didn’t inadvertently hook up the venturi fitting (not used with the RIO pump), perhaps the problem is with the injection port, preventing the creation of a fine and forceful enough spray for proper bubble formation. I suggest you contact AquaC (I will CC them here as well), and let Steve help you troubleshoot the problem (info@proteinskimmer.com)>> TIA, Kim Gilbert, Az. <<Regards, EricR…Columbia, SC>> Remora C Pro skimming wet, very wet... double posted. Grrrrrrrr     4/28/08 Hello WWM I recently purchased a Remora C Pro w/ a Rio 1400for my 120 gallon tank.

My tank was also skimmerless for about a year and I believe, because of the dissolved waste buildup, I too had very wet foam for a couple of months before it settled down. I found myself emptying the collection cup twice daily. Certain additives and foods will certainly add to the problem at hand. Running a filter with carbon/Chemi-Pure will also help calm the skimmer down, and is what I did. I too was in contact with Steve at AquaC. He even shipped me a new skimmer but the performance was the same. I can't say enough about the service at AquaC, is second to none. James <Thank you for this input.

Caulerpa prolifera, bad exp. related     2/16/08 Hello Crew, After reading many of the WWM Caulerpa prolifera links and FAQ's I would like to share my experience with this macroalgae. Tank: 29 gallon - BioWheel filter, 3 powerheads bounced off walls and moved 1-2 times/week, Fluval canister - carbon and sponge media rotated weekly. Water parmeters test normal - Ammonia 0, Nitrates always under 10, Salinity 1.023-.025, Temp - 79-80 F. Do not dose - weekly 4-5 gallon water changes with Instant Ocean salt. Excellent LFS test my water for other parameters that I do not test for and all are within normal range. (Because I don't dose, I don't regularly test for Calcium, phosphates, other trace elements - rely on the water changes and the LFS for tests every 1-2 months). The inhabitants are 2 false percs., a mating pair (4 clutches of eggs since Dec. '07) and they have been the only 'fish' inhabitants for 2+ years. Until recently, I had 4 hermit crabs (some 2 years old as well) and an emerald crab, happily there for almost a year. Tons of purple coralline everywhere, about 25 lbs live rock, several forms of red macroalgae, 3 thriving colonies of brown polyps and one lone mushroom (Ricordea) - polyps and mushroom also 2+ years in this tank. Several other types of macros - mostly red and not nuisance (Identified on your site - thanks!) Now to the Caulerpa prolifera - On January 2, 2008, I added a handful of the weed into my tank, along with a properly acclimated cleaner shrimp from my trusty LFS. The shrimp very sadly died within 48 hours - like it was being poisoned. I did water changes immediately and did not want to introduce another shrimp or any other creature. Within 10 days, my emerald crab was MIA and now presumed deceased. I am down to 2 hermit crabs. Polyps and mushroom are shriveled up and only partially extend after the water changes. Thankfully, the clownfish seem fine - still producing a clutch - but not like they were prior to the introduction of the Caulerpa prolifera. After reading everything I can find on your site and from the countless hours monitoring the health of my little tank, I think the Caulerpa is killing my inverts. Plan to carefully remove all of it today, followed up with even more rigorous water changes and increased carbon. I'll keep you posted on the progress. With a 29 gallon tank, the Caulerpa may be too great a risk - simply not enough water volume to handle any toxins released - even with water changes. Any thoughts on this matter? <Is a possibility here for sure> The recent problems in my tank brings me to another question. I do not have a protein skimmer because of the low bioload and frequent water changes and because the original inhabitants have been thriving for so long. <Mmm, would help> However, recent events have changed my mind - scared me, really and I'm going to purchase an HOB/HOT skimmer. Choices are the Tunze Nano or Aqua C Remora Nano (rated for 25 gallons). There are many reviews on your site - any personal preferences? <Both are excellent here> Do you think the Aqua C Nano is sufficient? <Yes, likely so> Is the Aqua C Pre-bubble box required? <Might be... try it w/o and see> (I don't plan to add anything else except 2-3 hermits and a cleaner shrimp if and when the polyps unfurl/things get healthy again) Thanks for this site and all your work. Cheers, Kellie McIvor <It will likely take a few careful vacuuming/water change procedures to rid yourself of the Caulerpa... but I'd proceed. I do encourage you to skim out the weedy bits, turf them into your garden and not down the sanitary sewer... if yours discharges more/less directly to the sea... as this noxious weed can be too-easily transplanted in this fashion. Bob Fenner> Re: Caulerpa prolifera 2/17/08 Hi Crew, <Kellie> Thanks so much, Dr. Fenner. <Just Bob, please. I have no doctorate> Here's a quick follow up to the Caulerpa situation. It's been 24 hours since removal of Caulerpa and water change plus carbon. So far a few of the polyps have opened up a little bit - tentacles unfurled but not at full 'blast' - more than they have in past few weeks. I take this as a positive sign and will continue with aggressive water changes. <Good> Skimmer should be here in a few weeks so hopefully this is the beginning of the end of this Caulerpa drama. A cautionary tale for small tanks, perhaps. Will keep you posted of the changes over the next few weeks if you are interested. Don't want to burden an already swamped site but this might be of interest to those with similar issues. <Thank you for your input, resolve to share> Also, as someone who lives 2 blocks from the Atlantic Ocean, I really appreciate the warnings this site gives about proper disposal of used water/algae/general tank gunk. Although I cannot fathom how the creatures live in such cold waters. Amazing world, eh? <Ah, yes; quite a planet> This site and your book have been real lifesaver. Thanks for the reply and all the Crew's hard work and patience. Cheers, Kellie <And to you. BobF> Re: Caulerpa prolifera control, Aqua-C...  03/14/2008 Hello Crew, <Kellie!> Another quick up-date on my 29 gallon tank. Happy to report that the frequent water changes and the addition of an Aqua-C Remora skimmer have made all the difference in the world. <Yay!> Polyps have never looked better - beautiful colour, fully extended and the lone Ricordea mushroom is huge now. The skimmer has been pulling incredible gunk every day. Also added a Chem-pure filter bag in my canister filter (with floss) and removed the Bio-wheel. The Caulerpa pro. pushed my tank to the edge but it was obviously not as healthy as I thought to begin with. I don't think my ramped-up water changes alone would have saved my tank from crashing. Skimmer has made all the difference. I resisted a skimmer for 2 years because I felt my weekly 20% water changes and very low bio-load did the trick. I was so wrong! All marine tanks need skimmers, especially smaller tanks! (Converts preach the loudest.) Thanks for your advice and expertise. Cheers, Kellie <Won't argue... Cheers, BobF>

Protein Skimmer for 28 Gal. 3/7/08 I was just wandering what in your opinion would be the best protein skimmer for a moderately stocked 28gal reef tank. Thank you! <The best is largely a matter of opinion, so I guess you will get mine. You should look at the AquaC Remora series. The nano can do a fine job for your tank, or you may want the full size Remora if you plan on a larger tank down the road. Welcome, happy reefing, Scott V.> Re: Protein Skimmer for 28 Gal. 3/8/08 Hi this question is for Scott V. <Here with you.> I recently asked what would be the best protein skimmer for my 28gal tank and after looking at your suggested remora nano skimmer (which was just great by the way!) I quickly realized that my previous question was not specific enough. <OK> You see money is real tight and as much as I would like to get a remora it is a little pricey. But if you say it is really that great than I will cut back and buy it but for now if it is at all possible than I would like to have another option or two thanks love the site! <The cost factor is one of the main reasons I like the Remora so much, it gives a good bang for the buck. There are cheaper skimmers out there for your tank, none of which I would recommend when compared to the small price difference for the Remora Nano. At around $140 it is quite the deal! A person would be hard pressed to even DIY a comparable skimmer for the price. Sorry for not having a better solution for you, but this is a case of you get what you pay for. Although I highly recommend the use of a protein skimmer, a system this size can be well served by water changes; 5 gallons a week can have quite an impact on water quality here. Thank you for all the kind words, Scott V.> Re: Protein Skimmer for 28 Gal. 3/8/08 The response I got from you was kind of what I expected, but upon further research I found an overwhelming amount of positive feedback for the Remora line of skimmers, the most convincing of which was your backing of the product so you will be happy to know that I have decided to buy the Remora Nano. Thanks for answering my questions so fast LOVE THE SITE! <Very welcome, thank you. Tis the reason I and other crewmembers like the AquaC line, as you have read! Have fun, Scott V.>

Aqua C Customer Service 2/29/08
Hi Bob,
Now this is what I call great customer service. Had a problem with my Aqua C.
See response below.
James
Hi James,
I didn't know you were part of the WWM crew! I've had the chance to hang out with Bob and several others (Pete, Mike, Eric, and Michelle) on several occasions - all great people!
I'm not sure what's causing the wet foam, but we can do one of two things. I can either send you one of the extended collection cups, which is taller and will give the foam more time to drain, or you can send the skimmer in for testing, and if we find any problems with the skimmer, we'll be happy to repair or replace it for you. If you want us to test it, you can just send that in to the address below along with a short note explaining why it's being sent in, and be sure to include your return address. Send me an email if / when you decide to ship that out, so I'll have an idea of when to expect it. Use a box large enough to have 3-4" packing material on each side of the skimmer (see attached diagram), and we recommend insuring the package as well. Let me know what you decide!

AquaC Remora Setup 2/23/08
I have just purchased a aqua c remora with maxi jet 1200 and am wondering how to attach the maxi jet 1200 on. Do I just slip one end on the remora and put the adapter on the other end and put the skimmer box over the pump and I am ready to go?
<This is exactly how you set this skimmer up, yes.>
A picture of how it should look when hooked up would be fantastic.
<I don’t have any pictures to offer, but I can direct you to the AquaC website where you will find PDF files on exactly how to set these up. Have fun, Scott V.>

AquaC EV240 Producing Microbubbles 2/16/08
Hello Gents - and thanks again for the fantastic resource. If only we all followed all the advice you give us!
<Heee…and if gas were back to $1 a gallon!>
Here's my dilemma - I have a 150XH fish only tank with a large wet dry and a Living Color coral insert.
I run an Aqua C EV 240 on my reef and have one for this tank as well.
I installed a new wet dry this week. Problem is that the skimmer is putting a tone of micro bubbles back into the display.
<Was it doing this before the new wet/dry? The same manufacturing residues/oils that can cause a new skimmer to spit out microbubbles are present in the new sump. You may just need some time.>
The sump is as follows - 40" long. From right to left, the tank drains into a 26" area of bio balls. I don’t have enough room in the cabinet, so I use a submersible Mag9 as the return pump. Due to the fact that the last area of the sump is the only 'open' area, it’s crowded. I have the Mag 9 tank return pump, the Ev240 and the Mag 18 that feeds the 240.
<According to the AquaC website this pump overdrives this skimmer and may need to be throttled down a bit. This could be playing a factor in bubble return.>
The skimmer water returns right to the area where the tank return pump is.
<Tough situation, even the slightest amount of bubbles will be returned to the tank.>
Unfortunately, I have VERY little space in that open area so I'm hoping to solve this problem.
Any ideas? I can call Jason Kim on Monday as well.
Thanks
J
<I would definitely contact Jason Kim for his input. In the meantime, you may want to try either some filter foam or filter sock types of materials between the skimmer output and the return pump to help catch the bubbles. Welcome and good luck, Scott V.>

Skimmer Pump Choices 2/11/08
With a slew of choices out there I am confused. I am presently looking at the AquaC ev120 for my 125 gallon tank.
<This is a good choice for this size tank.>
Also looking to purchase a rio 2100 or a mag 5 to power the skimmer. Your thoughts.
<I would choose the Mag over the Rio.>
BTW, noise is a factor in selecting the pump. Your thoughts pls
<You may also want to look at an Eheim or Oceanrunner pump of comparable flow; they tend to be much quieter and reliable. Have fun, Scott V.>

Skimmer Malfunction 1/10/08
Hi –
<Hello.>
I've run an AquaC EV-120 on my 75g for several years and it's been great. The other day it stopped foaming. Water and air are still bubbling
at the base of the foam tower, but no foam. This has happened occasionally in the past and it's usually because the water-intake valve gets gunk caught in it where it pinches down to create the spray.
<Happens.>
No problem; it's easy to pull out and clean (water and a dedicated brush are all I use). However, it did not resume foaming as usual. In thinking about the problem, I realized that I threw a sponge filter from my brand new quarantine tank into the sump at about the same time it stopped foaming. Is this the cause? Were there oils on the synthetic sponge that are temporarily changing the surface tension of my aquarium water?
<This could be the cause, it can happen.>
And if so, is this a temporary problem that I can wait out or should I do something about it?
<Should just be temporary. Maybe even pull the new foam out and your skimmer should start working within a day or so if this is the cause.>
Your thoughts are appreciated.
<Other factors could be anything else new to the tank (of course). Also certain foods or additives can cause this. I would also take a look at the skimmer’s feed pump to make sure the flow is unobstructed. You may even consider cleaning the impeller/magnet in some vinegar to decalcify. >
Thanks!
Ed
<Welcome, I hope this helps out, Scott V.>

Aqua C Urchin troubles 12/18/07
Let me thank you first for being a great source of info. But let me get right into my problem. I have a 65gal moderately stocked coral tank with a few small fish, 50# LR and a 20gal sump. After going through your site and the rave reviews I bought an Aqua C Urchin Pro with the Mag3.
<Yes, nice skimmer.>
The tank has been setup for about 2 years and the skimmer was installed about 2 months ago. The problem I am having is even with an under/over/under bubble trap in my sump, the tank is constantly being flooded with micro bubbles from the skimmer. I do not add any additives such as stress coat, and I rarely put my hands in the water. The sump is plumbed with sch 40 pvc. The sump flows about 400gph. I spoke with Steve at Aqua C, and he said it is normal for this to happen. It is very unsightly to see this in a show tank. Any suggestions? Thank you in advance for your help.
<A simple piece of filtration foam cut to fit between the baffles (I would put it where the water comes over and back under) will keep most, if not all, bubbles from reaching your display. Welcome, good luck, Scott V.>
Nitrate: undetectable
pH: 8.1
Ammonia: undetectable
Phosphate: undetectable
SG: 1.025
Calcium: 480
Alkalinity: 3 <meq/L I assume.>
Temp: 82 day/78 night

Aqua C Remora, op./noise issue  12/15/2007
Hey guys, love the site. I have a 26 gallon bow front FOWLR. I bought an Aqua C Remora with the MaxiJet 1200 3 weeks ago because of the info I found on your site. While it seems to be working well, about a half cup of gunk every few days. My issue is with the noise, in the instructions it says the noise and bubbles will decrease over time but has not. Being that the tank is in my bedroom the noise can get quite annoying. Is there anyway to decrease the noise?
<Mmm, possibly... by adjusting the flow, mix... or possibly switching out the pump (if this is the source of most the noise) for an Eheim hobby pump (MUCH quieter)...>
Or would it be ok to put the unit on a timer, maybe 12 hours on 12 hours off. Would it still be effective?
<Yes, might be the best idea here>
And would it cut down the life of the pump?
<Not appreciably>
Thanks for your help. -Joe
<Lastly, though it is not likely, this unit might be defective. If in doubt, do call on Jason or Steve at Aqua-C... they are both very customer service oriented... and fine young gentlemen as well. Cheers, Bob Fenner>

Quick Skimmer Question, Op., Aqua-C, surface skimmer attachment  – 12/11/07
Hello,
<<Evening>>
I just have a really quick skimmer question.
<<Okay>>
I have read on the WetWeb site, however have not found an answer...
<<I see>>
I just bought a brand new AquaC Remora Skimmer w/ the Maxi Jet 1200 upgraded pump for my 55gal.
<<A most worthwhile investment>>
I'm definitely excited about this upgrade, and it should be here within the week. My question is this: Can I attach the standard "surface skimmer" (not the item you can purchase from AquaC) but the "In store" version?
<<I’m not familiar with this device, but yes, it will probably serve>>
It's simply an intake tube connected to a regulator that, when attached to the pump/filter/etc. brings in water from the top and middle/bottom of the aquarium. (They sell for about $12 in most LFS's). I hope that's a good description.
<<Good enough, yes>>
I already own one, and don't think it will hurt to add, correct?
<<Agreed…as long as it allows the pump to pull in enough water/does not “starve” the pump>>
Also, I went into the LFS the other day and saw one of the best looking aquariums I have seen... It's the "Current Solana Aquarium Systems 34gal tank."
<<Ah yes…I saw one of these just this past week>>
This comes with a globe shaped silver housing for a metal halide light fixture.
<<Yes…looks quite interesting>>
Have you heard of these?
<<Only just>>
They're expensive, (at about $550 for all above) but they look great.
<<It is an attractive unit…though I do take issue with these “all in one” back-of-the-tank filtration systems as the filters/skimmers are usually lacking>>
Thanks in advance for your help!
Eric
<<My pleasure to provide. Eric Russell>>

Skimmer choice 11/29/07
Hey guys
<Hello Matt.>
I have a 400 liter reef with a Turboflotor 1000 protein skimmer which I’m not happy with. It only pulls about 1 inch of dark green stuff every week. I have 2 clowns, 3 snails, 8 very small unidentified hermits (can't find ID anywhere, but they do a great job of cleaning the sand of diatoms), and 1 coral. The tank is 2 years old and I have just noticed some hair algae starting to appear. I want to replace the skimmer. The two I like the most are the AquaC Remora Pro and the Deltec MCE600. The Deltec is more expensive but I believe it comes with a built in pump(?).
<Yes it does.>
Whereas the AquaC does not come with a pump. Any thoughts on these 2 choices of skimmer?
Thanks in advance. Matt.
<They have both been proven great skimmers, hard choice. This comes down to your personal preference. With the AquaC you will have a pump in your tank. If this bothers you then that may be your deciding factor. For the money I would personally choose the Remora Pro. The skimmer should help, but don’t expect a cure all for the hair algae, something is spurring its growth. You can read through the FAQs for more info, I would start here

Welcome, happy reefing, Scott V.>

Feel free not to post this. Unhappy with his Aqua-C  8/14/07
Hey all.
<Hello>
Based on what I've read over the past couple of months on this site, I purchased an Aqua C Remora (Maxi Jet 1200 pump) for my 65g mixed reef to-be. A week prior to adding 70lbs of nice, cured live rock (cured yes, but definitely smelling of a limited degree of decaying matter) from my LFS. A week prior, I began running my new Remora to "break it in", so it'd be ready to start skimming once I added my rock. Well, it's been a week now, and from the skimmer I'm getting the same daily collection of 1/5 of a cup of cloudy water that I was before adding the rock. Definitely not anything that would qualify as skimmate. When I move the O-ring down to raise the cup in hope of getting dryer foam, I get absolutely nothing. Feeling curious, and a bit frustrated, I decided to search the popular reef forums for other folks' experiences with the Remora. To my astonishment, I found the consensus of opinions regarding it's performance to be less then mediocre--and in many cases quite bad.
Now I consider your crew to be the most reliable source of info regarding this hobby, which is why I went out of my way to invest in the Remora. But I have a bad feeling that I was steered wrong in this case, and there are too many negative testimonials (check the "Aqua C Club" at RC) identical to mine for me to believe that I just unluckily received a "lemon", or that I installed a "peach" incorrectly. Yes, I will contact your friend in San Diego for technical advice. Just saying...
Sincerely,
Eric S.
<Everyone has different experiences with products, all I can add is I have been running an Aqua-C Remora for 5 years now and am very happy with its performance, but of course not everyone has had the same experience. I do encourage you to contact Aqua-C and see if they can help you out. I will add the perhaps the bio-load is just not high enough to get a lot of skimmate right now, but time will tell.>
<Chris>

AquaC – 7/3/07
First let me say what a terrific job you all do for the marine hobbyists. While I don't have a question today, I would like to use this forum to more publicly thank Jason Kim at AquaC for his courtesy, generosity, and rapid response. Mr. Fenner, et al, have frequently commented on the excellence of the AquaC skimmer products and, as I use an Urchin Pro on my 90 gal. reef, I couldn't agree more. These skimmers without a doubt offer the biggest bang for the buck. You have also commented on what a great person and business owner Jason is. Again, I wholeheartedly agree.
<Ahh!>
It is rare that products and companies fully live up to their advertising and marketing, but AquaC surpasses expectations as a product and a business. Please pass this along.
<Will do so>
Once again, thank you, Mr. Kim. And thanks to the folks at WWM.

Skimmer types... Not liking his AquaC  – 07/03/07
Hi crew-
Thanks for a wonderful aqua portal!
I have a CPR SR-4 in the sump of my 75g reef tank.
I am not sure about the efficiency of "Rejuvenation Venturi Technology", as they call it, and have not been thrilled with the nutrient export performance of this skimmer.
Are these low-grade skimmers?
<Mmm, no, not IMO>
I have been considering an upgrade to a used Euro-Reef RS80.
<Also a good unit, product in my estimation>
Any sense of how much better this unit might perform?
<Perhaps a bit better, but not a big difference>
Got any advice for me?
So long (and thanks for all the fish)
jimgray
<Heeee! It may be that the make-up of your system/water at this point has little to skim... Bob Fenner... Not Doug Adams, but alive... and will gladly settle for the difference>

Big Change: Water Evaporation   6/24/07
Hello WWM,
<Hello, GrahamT here tonight!>
You are a tremendous resource and we can't thank you enough for the time and effort your whole team puts in to making this wonderful hobby even more enjoyable. The daily questions are a daily read for us - more so than the newspaper. Thank you again.
<Thank you for your kind words on behalf of our dedicated crew! I am convinced that reading the dailies... well, daily, can make an advanced hobbyist out of any of us!.>
We have a 75 gallon FOWLR which has been running nicely for three years now. As per your recommendation, we upgraded to a Remora Pro skimmer about six weeks ago. This has been maybe the best thing we have ever done for our tank. Producing an incredible amount of the nasty green stuff.
<Very good to hear. Some people can fine tune the amount of food they give by the amount of gunk collected in their skimmers.>
When we first introduced the skimmer, we had a difficult time keeping the temperature steady as the Mag 3 pump gave us 4-5 degree fluctuation daily. It was easily fixed by adding a small fan blowing across the top of the tank.
<Ahh, yes... evaporative cooling can be very useful and economical.>
Our tank temperature is now consistent at 76 degrees. The problem we are having is with water evaporation.
<Hence the term, "Evaporative cooling".>
Before adding the skimmer, we would have to add a couple gallons every couple days or so. Now we have to add three to four gallons per day.
<Happens, I'm afraid...>
There are no leaks anywhere and we are wondering why this is the case. At first we though maybe it was due to summertime, but we haven't had this issue in the past.
<You're experiencing one of the drawbacks to evaporative cooling. Really, there isn't much to say here, since slowing down the evaporation means warming the tank. You should be ok with letting the temps rise slowly to 78-degrees, if you have a lower speed for the fan you use. Other than that, I think you're stuck with it. One thing you need to watch out for with increased water-loss through evaporation is the problem of concentrated "leave-behinds" that are being reintroduced every time you top-off, and as the water leaves, the levels are rising. If you use purified water and perform frequent water changes, this may not be a concern. Food for thought...>
Thanks in advance for your help,
Tracy and Scott
<You are most welcome, folks!

Remora Skimmer Broken?  6/23/07
So I have a 55G reef tank with a variety of soft corals, inverts, and a small number of reef safe fish (anthias, shrimp goby, etc.) I have a HO filter that I run chem-zorb and Purigen in. Tank has been up and running for two years. No problems, no worries.
Ammonia/Nitrite 0ppm
Nitrate 5 ppm (But steadily Rising)
Calcium 450ppm
<A bit high... your alkalinity hopefully isn't suffering as a consequence... I would be testing>
Anyway the core issue of this question is the protein skimmer. I have an aqua remora HO that over the course of the past month has decreased the amount of waste until it is now not producing anything.
<Happens... your system is "centering" in a fashion in which there isn't much of anything to remove in this fashion>
I have contacted Steve at AquaC and he is trying to help but seems to be out of options. I have cleaned and scrubbed the whole unit,
<Highly unlikely it's the skimmer itself...>
including removing the screw on top and cleaning that passageway. I have the optional box that the pump sits in. A few days ago I picked up a new pump praying that would solve the problem, it didn't. The water just isn't reaching the tube, it isn't really even close. According to Steve replacing the pump should solve the problem. Is there anything that can be broken, or wrong per se with the skimmer unit itself?
<Nothing likely "wrong" here period>
Nothing else with the tank has changed. There is no new equipment (besides the new pump), there is no new livestock. The feeding has never changed from two frozen Mysis cubes per day. I just can't figure out what the issue
is with this because, as you are well aware, the skimmer is essential, vital to the health of the tank. The corals already look unhappy, I am doing frequent water changes to try to compensate.
Any thoughts?
Much appreciated.
<I would NOT worry re... but I WOULD keep it running... and measure your alkaline reserve. If you'd like to read re other folks having the same experience you can scan the WWM FAQs re Skimmer Op./Maint... Bob Fenner>

Re: Remora Skimmer Broken?   6/24/07
So there is an interesting update to report. I took my other remora skimmer, same kind of unit, same kind of pump, off of my FOWLR tank and installed it on the reef tank where the skimmer is not producing anything. Within minutes the skimmer from the FOWLR tank began producing thick, copious amounts of waste. So I wonder again, can the skimmer itself be broken? Two remora units, the same age, the same pump, the same tank, one works one does not. And the one that does not has the advantage of the skimmer box and a brand new pump. What could possibly be wrong with this skimmer? Thoughts?
Thanks again.
<Mmmm... either the aspiration device or... I'd ship it back to Aqua-C for their look/see. B>

Skimmer Installation – 6/8/07
Hey. <Hey!> I have a question about installing my protein skimmer. I recently purchased an AquaC Remora Pro with a Mag 3 pump for my 55 gallon mixed reef. I have a medium to high bioload so I went for the bigger skimmer. <Smart. I wish I had gotten the pro version.>
I'm writing because I read somewhere that skimming is much less efficient if the water is drawn from anywhere other than the top inch of the aquarium and would like your opinion on this. <True, but may be exaggerated.> I have recently noticed quite a bit of dust and oil on the water's surface but unfortunately have no way of installing a sump or any sort of overflow in my current setup. <I threw together a siphon overflow box and a sump made from a Rubbermaid container, returning with a Maxi-jet 1200. Very simple. At a minimum, you can and should remove the dust and oil with paper towels by hand. Even a skimmer box might not get a persistent oil slick.> I wanted to run an idea by you and was wondering if this is worth doing and if it would work. I wanted to install a few elbows and a short section of pvc pipe to basically bring the prefilter up horizontally at the very top of the aquarium. This would draw the water from the top 1-2 inches of water and maybe even some from the surface, all depending on water level of course. I understand that this runs a risk of sucking in air <yes, would have to keep the perfect level constantly for this to be at all effective> and even possibly running the pump dry and burning out the motor, but I top my tank off everyday and would install it low enough to compensate for a few days evaporation. This would of course extend the length of the intake pipe and add a few turns to it. I estimated the total length of the intake pipe including the 3 elbows would be about 15 inches. Do you think this would significantly reduce the pump's output? <Yes, and this is the biggest thing affecting the performance of the AquaC skimmers.> Is this something worth doing, or am I just making things difficult? <I think this is over complicating it. They do offer a skimmer box to fit over the pump that will accomplish this for you with fewer losses. If you want to DIY, you could use the concept of a box with slits at the top as a container for your pump, instead of inline piping. I personally found that the reduction in pump efficiency from being in the box was more than the benefit of skimming from the top of the water. Mine skims best without the skimmer box. And you will have the same problem with the fluctuating water levels. When the tank water drops, the pump will suck air and you have to train any house mates and tank sitters what that means to avoid burnt out pumps, or get an automatic top off system. Much easier to install a sump.> Thank
you for you input. Jon
<You are welcome. Alex.>

Remora Skimmer question   5/24/07 Hello Crew, <Ed>    This is my first question submitted to you.  First off I'd like to thank you for your time and your website which I have found to be an invaluable resource as a beginner in reef keeping (which is the very reason I've not had to actually submit a question until now).    A little background; I have recently set up and cycled a 42 gallon hex with about 50 lbs of live rock and 3 inch sand bed (mixed coral sand and live sand).  It cycled relatively quickly (about 2.5 weeks) I think because I got a really good batch of cured live rock.  When levels reached 0's I added my cleaning crew, which have been doing great so far.  No corals or fish have been added yet.    My question is in regards to my Remora Protein Skimmer.  It's been running since the start and has been skimming OK, but I noticed there are a few gaps in the divider between the intake and the output compartment. Sometimes there's alot of microbubbles escaping directly back into the tank since the gaps are very close the top of the divider, right where the output ramp sits.  Is this normal or should the two compartments be completely sealed from one another? <Mmm, am referring your question to owner/manager Jason Kim here... But I suspect all your skimmer needs is a bit more "break in" time with your still-new system...> If sealing is needed, what should be used to close the gaps?  Thanks for your time and keep up the great work! =D Ed Gambler <Thank you. Jas? BobF>

Remora question resp.   5/24/07 Hi Ed, Bob at WWM forwarded me your message, I can help out.  I'm not exactly sure which baffles you are talking about, but allow me to explain what they should look like.  There are three baffles inside the Remora - one of which is located deep and somewhat hidden, so I doubt you are referring to that one.  The other two baffles - one is long and runs the length of the skimmer body, and the other is much shorter and shaped like an "L".  The long baffle should be solidly connected to both sides of the skimmer body - you shouldn't see any gaps along its length.  A gap along that baffle would be a manufacturing defect, and we would replace your skimmer with a new one. The smaller L-shaped baffle should be glued to one side of the skimmer body, and there is a small gap along the other side of the skimmer - it isn't sealed off completely.  The reason for this gap is to allow excess water that splashes around due to the spraying action, to drain back into the skimmer body. It sounds like you might be looking at that gap? One of the reasons your skimmer is releasing extra microbubbles is due to the fact that your tank is so new, with no livestock, and relatively fresh live rock.  Any of those factors would probably lead to a microbubble problem, and you've got all three at the same time.  Over the next few weeks, as your tank matures and you begin to add fish and/or coral, you should definitely see a reduction in the number of microbubbles.  Nothing to worry about now, although I know it is an aesthetic nuisance.  Certain water conditioners, trace element supplements, etc. can also contribute to this situation, so let me know if you are using anything like that I can figure out if they might be playing a role. If you have any other questions at all, don't hesitate to contact us! Jason Kim President <Thanks much Jas... Man, you're quick! BobF> AquaC, Inc. visit us online at... www.proteinskimmer.com

Re: Remora question   5/25/07
Hi Bob,
    Thanks so much for forwarding my question to Jason Kim at AquaC.  Turns out their office is right down the street from mine so we've resolved the
issue (in record time taboot) and I'm going there tomorrow to see about getting a replacement.  You guys rock!  =D

     It is indeed a small world.  Are you in San Diego as well?
<Yes... same zip... 92126, in East La Jolla... Okay, Mira Mesa...>
    Quick update:  I met with Jason this morning and he confirmed that yes my skimmer was leaking through the main baffle and he provided me a new skimmer body as well as letting me keep the old one (which I think I can seal and use as a backup or for another tank later).  Jason is a super nice, stand up guy for sure.  Thanks again for hooking me up.  I think you've helped me more in setting up my new tank than anyone...and you didn't even know it!  I greatly appreciate you, your time and knowledge and your website  =D

AquaC EV120, A satisfied customer   5/20/07
Hi Everyone!
<Hi David, Mich here.>
I am currently in the process of curing my live rock.  I have a 125-gallon tank with a 25-gallon sump and a 50-gallon refugium with 150 pounds of Lalo rock from Drs. Foster Smith.  I chose the EV120 as the best skimmer I could afford based on my research.  
<An excellent choice!  I too use an AquaC Skimmer and am very impressed with its design and performance.>
I had it running for about  2 to 3 weeks and then all of a sudden when cleaning the collection cup I noticed millions of cracks radiating from around the drain fitting, some inches long.  
<Uh-oh!>
I contacted Marinedepot.com who I had purchased it from and copied in AquaC.  My Email was sent on a Saturday. By the end of the day I had a response from Marinedepot.com.  On Monday I was contacted by both Marinedepot.com and by several people at AquaC, the president of AquaC included.
<Yes, Jason Kim and Steve Prince are wonderful people, both professionally and personally.>
The replacement part was shipped on Monday and I had it in my hand by Thursday.  I offered to ship back the old cup but they declined so I didn't have to do anything but send a few emails.  
<I'm not surprised.>
I have never had a problem with a product that was resolved so easily without mounds of paperwork, hours on the phone etc. The people treated me like they were getting a huge sale from me, not just fixing my small problem.  
<This is wonderful to hear.>
Marinedepot.com does not always have the cheapest prices on all items, but there is a whole package to consider.  Getting a problem like that fixed immediately is worth paying a few bucks more.  
<I would attribute your positive experience more to AquaC, they have a reputation of producing a high quality product with superior customer service, not that there is anything wrong with Marinedepot.com.>  
The EV120 works like a champ, I can't empty it fast enough. It quickly fills with a thick density green foam. When I go to work I put the hose in a 5-gallon bucket because I am afraid it will pull out enough to flood my utility room.
<Yikes!>
The design is also easy to clean and quiet.  
<Yes.>
If you are in the market for a skimmer I would definitely buy one from Marinedepot.com.  I stumbled across AquaC here so thought you might like to know my experiences with them.
<Thank you for sharing!  It is always nice to read a letter of satisfaction!>
Sincerely,
David Matza
<Again, thank you for contributing!  Mich>

HOT about Aqua-C’s HOTB Skimmers…  – 05/07/07
I've been in the reefing hobby for a couple years and the fish hobby as a whole for around 20 or so.
<Okay…>
I've built my own skimmers and have modded many as well.  
<Neat.>
I'm not quite sure why the aqua c remora pro is still recommended by your moderators?  
<Oh and on to the meat of the query…a loaded question…Well Luke unlike you I’m not going to list my aquarium credentials here I’m just going to let facts and logical anecdotes speak for themselves.  First off you said moderators so I don’t know if you meant those who keep up our chat forums or the crew who answers queries…..I’ll assume it’s the latter. I know that me personally, and many current and past members of the crew including Bob (as seen in his writings, advice) have had very good experiences with the Aqua-C company as a whole.  They are consistent at building quality equipment that is simple yet effective to use, when used properly. Many aquarists send us in anecdotes on there dealings with the company, and have told us that they are not only very helpful when it comes to advice on their products but are very professional and quick to respond to problem arising with the products…helping their customers troubleshoot and make the product work as it was intended.  As far as the remora-pro, I recommend it to the casual aquarists on a regular basis because of it’s simplicity of use for the most part and the reputation of the company, rather than fringe companies who are “iffy” untested.  While there are better skimmers out there, the Remora is still near the top of the list for hang-on applications.  In fact the only Hang on skimmers I prefer to it are the Deltec…but it is considerably more pricey.  I understand that you are a DIY and modder type guy but you have to understand that most aquarists are not.  I find it also important to point out that we do not recommend this product exclusively it is simply another option that we give, there are other brands mentioned just as much in the FAQ’s.>
The remora pro is an outdated skimmer
<How so? Most skimmer designs haven’t changed much over the years other than that some of the previously high end-designs have become more economical for the public to own, i.e. recirculating models and that brands previously not attainable in the U.S. are now available, i.e. bubble king, Deltec and H&S.>
that may have served well years ago but has been surpassed by many cheaper alternatives.
<Again proof, examples please…data?>
The remora pro says it will pull a full cup of dark green skimmate once every two weeks, no matter how large the system.
<Well first off I wouldn’t use the remora pro on a system that is 80 gallons or larger. Again the remora is made to feel a niche, as a hang on skimmer and it does this application quite well…are there other larger skimmers that are better suited to larger systems…of course. And personally I have seen the remora, and many other skimmers, pull out a cup of day of skimmate when properly tuned; see Anthony Calfo's writings for more on skimmer adjustments in general.  Another thing to keep in mind is that the Aqua-C’s use a different design than most of the other skimmers out there, air-induction I believe they call it…while a lot of other companies seem to go the way of the needlewheel or Becketts.  All designs have there pros and cons and it is a personal choice...my observation with the Aqua-C’s is that they are more difficult to break in and fine-tune but once they are, work just as well as any other design.>
A cup every other week is far from decent imo <”In my opinion”>
<Mine as well, and again set-up properly your skimmer should be able to produce more than this, please do see the Anthony Calfo readings I mentioned.>
and I just wanted to see what the reasoning was behind this.  
<Well you have my answer but as far as I can see you aren’t attempting to converse really….you may want to contact Aqua-C directly.>
The Bermuda HOT, D&D typhoon, Odyssea ps160 and a handful of others are much better and much cheaper.
<Cheaper yes…better I’d be inclined to disagree. Keep in mind that experiences are anecdotal and that many aquarists are not willing to modify and tweak…we live in an instant gratification (plug and play world). whether that’s good or not, that’s how it is.>
Just wanted to pass along the info.
<Duly Noted my friend.>
And keep up the good fight, you guys do a great job with the volume of questions you get and this site has great info available.
Thanks,
<Welcome.>

Aqua-C input, who is this?  – 05/08/07
Thanks for forwarding Bob, I have no idea who that is.  I appreciate Adam's response, he took a lot of time to write that out!  Feel free to have Luke

A Positive Note on Aqua-C's Skimmers...
Dear Adam or whatever crew member may be responding to this,
<Adam at your service...on the self-appointed insomniac shift.>
I was reading the daily FAQ's, which I find interesting and resourceful.
<Thank you.>
You recently had a fan write in about how the Aqua C skimmer is inferior and outdated. I just had to laugh out loud to myself. This isn't a question more than it is a statement. I personally own an Aqua C Remora, and it has performed nothing short of outstanding. I encourage your team to keep encouraging your readers to purchase one of these fine skimmers. Not only is
the company more than willing to assist the average customer, their product does exactly as they claim. Once again, I found it amusing how many people write to the crew with ridiculous opinions and excuses. Keep up the sound advice,
<Thank you for sharring, Eric.>

Skimmer Problems...Looking For New Choices - 05/01/07
Hello,
<<Morning Ron>>
I was hoping that someone could pass on a little guidance and possibly some past experience.
<<Happy to share what I can...>>
My skimmer malfunctioned over the weekend causing a major flood.
<<Mmm, yes...does happen...and one reason I am fond of "in-sump" skimmer models/installations>>
I have been wanting to replace it (AquaC Remora Pro) because I have not been happy with its performance.
<<Hmm, generally a very good skimmer choice.  Have you tried contacting Jason Kim (owner) at AquaC?  I am sure he would do his best to help determine/fix the problem>>
There are so many choices and everyone says this one is great and that one is excellent.  Very confusing.
<<Indeed...and does help to hear from those who own/use the models you are interested in to help "you" make an informed decision>>
My setup is a 75 GAL with a 37 Gal sump.  My quantity of live rock is increasing every month.  I have a moderate fish load; four Tangs and the rest is small stuff.  I would like to start adding corals to the tank.  The skimmer and live rock are my primary filtration.
<<I see>>
Could you offer any suggestions to help me make a sensible choice?
<<I think I can, yes.  My current fave skimmer is the Euro-Reef.  I employ an older model CS12-3 on my system...I think the RS100 would be about perfect for your system with an average stocking load, or the RS135 if you plan to stock heavy.  Though I haven't used one myself, I've been quite impressed with what I have seen of the H&S skimmers...quality construction employing Eheim pumps...and the performance looks very similar to the Euro-Reef in my experience.  Either of these skimmer brands would serve you well>>
Thank you for your time,
Ron
<<Happy to assist...  I do think the AquaC line is also a good choice, especially for systems in your size range (excellent quality/value for the price)...perhaps their in-sump model (Urchin Pro) would suit better.  Regardless of what brand you choose, I suggest you still give Jason a call and discuss your issues with the Remora Pro.  EricR>>

Re: Skimmer Problems...Looking For New Choices - 05/01/07
Thank you so much for your help; it's time to do a little comparative shopping.
<<Yes indeedy>>
I will definitely contact AquaC.
<<Please do, at least give Jason the opportunity to address your concerns/issues...you may find you don't need another skimmer after all>>
Thanks so much.
<<Quite welcome.  Eric Russell>>

AquaC - EV-180 Collection Cup Drain – 4/17/07
Hey Guys
<Hi Jim, Brenda here>
Quick question on an EV-180 I just bought 2nd hand.  The manual states that using the collection cup drain is optional.  However, they don’t tell you what to do with it in order for the cup to fill past it if not using it?
<You will need to empty the skimmer’s collection cup when it gets to this point.  <<Or plug it. RMF>> Why not use the drain option?  All you need is some tubing connected to the drain, use a small plastic container, such as a 12 oz. soda bottle.  The collection cup on the EV-180 is not very large.  It will likely need to be emptied often to be functioning properly.>
I know this may be a dumb question, but my last skimmer (Urchin Pro) didn’t have one, and I don’t really have room to add one either.
<This skimmer will usually take some getting used to, and some adjusting.  AquaC has great customer service.  I have had to contact them myself when I first started using it.  Don’t hesitate to contact them.  Their website is: http://www.proteinskimmer.com
Thanks, Jim B.
<You’re welcome!  Good luck with your new purchase!  Brenda>

Re: AquaC Drain   4/19/07
Bob,
   I seen your suggestion from yesterdays FAQs regarding plugging the AquaC EV-180 drain.  It won't skim if you do this.  It is important that that drain remains open.  Once the skimmate reaches a certain level in the collection cup  (without using the drain) it will stop skimming.
   Brenda
<Thank you for this... of course, the cup has to be drained at some point... but I thought the capping would give the reader/s more time twixt... Will accrue. BobF>

Re: Was: Mercury UV sterilizer bulbs, now more skimmer, AquaC ref.  2/28/07
Bob,
Thanks so much!  I agree about the opportunity cost issue.  Good point.
Turns out my city offers a "toxic waste day" once a year they will take whatever you have and deal with it.
<Ah, good>
  This is not a huge issue, but I think I needed something else to worry about for a break from worrying about the dang BGA.
<I can and do understand>
To clarify, my sump is about 10 gal of water in a 19 gal Rubbermaid container.  I am never sure which measurement to describe.  The amount of water seems most relevant.  I agree, I will be doing more with this area very soon.  It is the weak link in my system.
<Ahh!>
I threw it together to try and keep some algae going for my tangs, and the algae didn't make it, but I like having the increased water volume/surface area and a place for critters to grow.  I will be upgrading this area soon.  I did get a real overflow box to replace my homemade one (which worked but didn't have enough elevation change to get a fast flow rate).  I will be reading and planning to enhance this part of my system.
<Good>
This morning my tank looked awesome before the lights came on, not much algae to be seen.  Afraid to get my hopes up as it always goes crazy during the day when the lights are on, but it did look significantly better.  The UV installed last night could be helping already with the water quality.  I will let you know how this turns out.  If the UV makes a significant difference in the algae, I'd like to share that with others.  
<Please do>
Speaking of lights, I see conflicting views on the impact of lighting on the BGA.  I don't think my lighting should be a problem, although it does grow like crazy when the lights are on, and recede when they are off.  I have a brand new Coralife Deluxe PC w/ daylight and actinic (4 x 96 W total).  There shouldn't be a problem with dimness or frequency shifts.  I have not tried starving it of light, as that doesn't seem to be recommended and doesn't seem like it would be too good for the other tank inhabitants for very long.
<Agreed>
  I had half the wattage before this new fixture, also PC, and the new lights had no effect on the algae (nor did replacing the bulbs in the old fixture).
<Other issues...>
The area I have been struggling with is my skimmer, which I added hoping to fix or at least improve the algae problem.  I searched all your skimmer pages for details about what else I could possibly tweak to get more out of my Remora.  I emailed Steve at Aqua-C,
<A very nice fellow... He and Jason (Kim) were out visiting a few months ago in Hawai'i... They are "fishing fools!" as well as earnest entrepreneurs.>
and he felt I am getting enough skimmate (under 1/4"/day usually).  I think I should be getting more, with 3 tangs, maroon clown, a damsel, a flame angel, watchman goby (15 inches total fish) and a few shrimps and crabs, Xenia, Euphyllia, mushroom polyps, Zoanthids, and live rock.
<Mmm, the amount and quality of skimmate depends much on other influences... that you are getting some is indicative that the unit is working...>
Last night I tried taking off the skimmer box (I know that should only make it worse)
to see if easier flow to the pump might help, and had 1/2" this morning, an apparent improvement, but that doesn't make sense.  The only other thing I can tweak is the water level in the tank. I had already raised it some and that seemed to help the first day, but then it dropped back off.  Do you know what water level might be optimal for the Remora with the Maxi-jet 1200 pump?
<About half an inch of water below the collector cup...>
Do you know what else I can try to improve its performance?
<Definitely no more or better than Steve or Jason>
I used to have a modified Lee's (I made it longer), which worked really well, but replacing the wood diffusers was really the only problem and everyone said we had to go venturi.
<This is a feeble unit... only fine for very small, way-under-populated systems...>
Then I had a useless Sea-Clone (bought right before I discovered your site!!).  I was expecting great things from the Remora.  I am afraid I am missing something obvious, or I got a dud.  It seems pretty foolproof.
<Is... likely your system is in a sort of "balance mode"... not much to actually skim>
  But I know there is a lot of nasty stuff in my tank, and am not getting as much skimmate as I should.  I have cleaned the injector.  The collection cup is set to the lowest point.  I am out of ways to tweak the unit.  I have tried cleaning and tried not cleaning the riser tube.  Should I try a different pump??  
<Mmm, not likely... Do give Jason.K a call here though>
I would really like to have to empty the cup every day or at most every other day.
I should have good oxygenation, good water movement (filter, sump return, 2 power heads, and now UV return), good lights, mechanical/chemical filtration (Emporer w/ bio-wheels, alternating change of filter cartridge), denitration from live rock and small plenum and aragonite substrate (still trying to read and understand why some of you don't like this substrate).  SG 1.025, nitrates 0, phosphate 0, pH 8.2, Ca 360, alk 8.
<Do check your Magnesium...>
Haven't retested since adding 2-part Ca/buffer (Kent) a few days. I expect Ca and alk to improve.
<What you relate is fine>
Before I had any coral I maintained Ca and buffer from aragonite substrate and water changes.  Increased demand is affecting this I think.  And I got a 32 gal Rubbermaid trash can to get set up to do larger water changes with aged water, as I have had to do 5 gal changes with my current tools.
I'm hoping my husband doesn't notice the lovely 32 gal trash can sitting in the dining room. Ha!  Oh, where do you get the dolly for moving the trash can?  Can't find at Wal-Mart or Lowes.
<Try a "Maintenance" or "Janitorial" supply type of store... Out in the west we have "Smart & Final's" that offer very nice Rubbermaid Brute units...>
If any of you have any ideas about how to further tweak my Remora, I would greatly appreciate it!
Thanks,
Alex Miller

Aqua C EV 200 question   2/6/07
Hello,
I have a question regarding the older Aqua C EV 200.  I recently purchased a used one of these for my future 240 gallon setup.  I am upgrading from a 135 reef.  The 240 will have SPS, LPS, and a fair fish load.  Will this skimmer be sufficient or am I in trouble?
<Mmm, I'd upgrade myself>
Also, I am wondering what the most efficient way to plumb this is.  I have seen the changes made to the newer EV-240 model and am wondering if the EV 200 can be modified to increase efficiency in any way.
<Mmm, I'd contact Jason Kim at AquaC (addy on WWM) and ask re>
  Also would like to have the Calc reactor output flow into it as the new EV 240 does.  Any thoughts or suggestions?  Thanks,
-Jason
<I'd have this discharge directly into the sump myself. Bob Fenner>

Protein Skimmer For A 210 Gallon Tank 2/1/07
Dear Crew,
<Paul>
I have a brand new Aqua C Remora HOB protein skimmer. I originally planned on setting up a 75 gallon FOWLR which is what the Aqua C was planned for. However, good fortune has allowed me to get a 210 gallon tank instead.  I know the Aqua C would not be enough for this size tank.
However, I can't return it and know how well they work.  In your opinion would I be okay if I added another Aqua C Remora and use two together.  Additionally, since I will now be able to have a sump, would it be okay to use the HOB type and one in the sump.  I thank you for your time and help as you have assisted me in the past as well.
<Sure, no such thing as overskimming.  You may be surprised with the AquaC HOB.  My feeling is they are underrated and you may be fine with this providing your animal load isn't too high.  If nuisance algae starts to invade the system, then go with an additional skimmer.  You may want to try and sell it on EBay or elsewhere and just buy one large enough for your tank.

One comment and two questions, Aqua-C, mud in a 'fuge and feeding Scler.    1/27/07
Hello WWM Crew,
<Bart/holomew!>
Thanks you so much for the wonderful service you provide.  I wanted to comment on the great service I received recently from one of your sponsors.  I love my Aqua-C skimmer!  The O-ring dried out and cracked (as O-rings do). I made one phone call, waited two days and TWO new O-rings arrived in the mail.  No muss, no fuss, and NO CHARGE!
<Hee heee, Freeeeeee!>
This is a great company and they will be skimming for me till I no longer need to skim.  Now, two quick questions if I may:  I am running a closed-loop return manifold that I constructed using Anthony's informative article on my 72 gallon bow-front reef system.  It was fun to build and works great with the old-style external Quiet-One pump that I have.  My question has to do with the intake.  I used my miter-saw to make cuts half-way through a ¾" piece of PVC to make a strainer.  Over this I have placed a coarse sponge filter to keep the tiny snails I have all over my tank from getting into the pump.
<Good design>
  I dislike the sponge filter because I have to clean it and because I suspect it is a source of nitrate in my tank.  It is the only mechanical filter I have on the system as I use a refugium and skimming for water treatment.  Do you think I could remove the sponge?
<Mmm, no, I'd leave it, or something similar in place... as a screen>
  Would the tiny snails be able to stop the pump?
<Possibly, yes... and/or cause trouble in being crushed, dissolving...>
Secondly, I have an assortment of Caulastrea and Euphyllia corals (widely spaced, of course).  Do you have a recommendation as to a food of the appropriate particle size for feeding these animals?
<A mix of live or frozen/defrosted zooplankters... "of small size", 1/16" diameter nominally will do>
I suspect the Mysis I feed the fish is a bit large for these corals to utilize.
<Yes, likely so>
Thanks again for the good work you do.
Best Regards,
Bart V

Quiet and Quality Protein Skimmer    1/5/07
I have a 50 gallon salt water tank with fish and live rock.  I currently use a Prizm Deluxe PS-RS50181 Protein Skimmer.  Though the system works great, I makes too much noise.  What other options do I have for a Protein Skimmer that is "quiet".  
Thanks in advance for your help.
<I highly recommend the Remora AquaC; in fact, based on personal experience and reviews, it's likely the only skimmer I'll ever use. Best regards, Jorie>

To Upgrade Or Not? - 12/12/06
Good Afternoon Guy's & Gals:
<<Good evening Jeremy>>
I have a quick question that I value your opinion of.
<<Okey-Dokey>>
I have a 75-gallon reef tank with a 20-gallon sump.  I currently have an AquaC Urchin skimmer rated up to 75-gallons.
<<Great little skimmers...and I had the pleasure of meeting the company owner at Bob's place in HI last month>>
Do you think this skimmer is undersized for my setup?
<<Probably not...These skimmers are "sized" very accurately...unlike the boasts of many of the lesser quality skimmer manufacturers>>
Should I look to upgrade to something a bit more substantial?
<<Up to you...why not give Jason Kim a call at AquaC (or send an email) and see what he suggests?  I'm certain he won't steer you wrong>>
The skimmer does pull out about a half a cup dark skimmate every 3-4 days.
<<Much like "watts per gallon" for lighting, there are many factors to determine "how much skimmate" your tank should be producing.  Rest assured you have a quality product>>
Bioload consists of:
*Fish:* Yellow tang, 2 blue-green Chromis, convict blenny, pink skunk clownfish, algae blenny *|* *Coral:* Ricordea yuma mushrooms, yellow polyps, devils hand (Lobophytum sp.), frogspawn (Euphyllia divisa), Torch (Euphyllia sp.), various Zoos & 2 Acropora frags *|* *Inverts:* coral-banded shrimp, 10 blue-legged hermit crabs, two astrea snails.
I plan to add maybe 1 more fish and a lot more corals.
<<Do keep in mind that "corals" place a bio-load on the system just as fish do, albeit usually somewhat less...and not without other considerations such as allelopathy>>
Your input is appreciated.
<<Hope you find it useful>>
Jeremy
<<Regards, Eric Russell>>

Protein Skimmers...Tiny Bubbles Do Not Make Me Happy 12/8/06
I'm hoping that someone there can help out with a question in regards to protein skimmers. I have an Aqua C Urchin Pro driven by a Mag 3 pump. When I turn it on it fills the top <of the> tank with micro bubbles within minutes. I have tried turning it on with different water levels in the sump, I tried all possible cup placements, no luck. I contacted Aqua C and went back and forth with them a few times and they feel it is something in the water.
<I tend to go along with them.  Some additives can/will cause this.  Have you used any additives recently?>
It's a 75 gal. tank with a 37 gal. sump. I moved the water from my 50 gal. tank into this setup and filled the remainder with saltwater that I mixed from an R/O.
The tank has been running for approximately 4 weeks. I can not run the skimmer because it fills the tank with micro bubbles.
<Ahh, did you put any Stress Coat or similar product in the water on initial set-up?>
At this point I would like to consider replacing the unit out of frustration. I have been on your site and have become very confused, some people swear by the ETSS, then others say it's too loud and cumbersome to clean because of the bio balls. Others say that Euro Reef with an Eheim motor and not the proprietary motor from the manufacturer is the way to go.
<All good skimmers, and the Euro Reef/Eheim combo is a good choice.  The Eheim pumps seem to last forever.  I like skimmers that offer the least amount of adjusting/tuning, etc.
I'm using a Tunze and find this skimmer to fall into that category very much.>
Based on what I have described can you offer any suggestions which would make this decision easier?
<I wouldn't throw the towel in yet.  Get yourself two units of Chemi-Pure and place in the sump where some water flow will go through the bags.  If there is anything in your tank that could cause the micro bubble problem, this will remove it.  I feel the Aqua C skimmers are a very good and hear very few complaints about them.>
Thank you very much in advance for your help,
<You're welcome.  James (Salty Dog)>

Re: Protein Skimmers...Tiny Bubbles Do Not Make Me Happy 12/11/06
Sorry I just noticed a typo, I meant to say that I did use stress coat <Stress Coat> when I made up the water.
<This will definitely cause your bubble problem.>

><Does need to be submerged or have water flowing through it.  The Chemi-Pure, depending on the flow rate through it, should take a couple days to remove the Stress Coat.  Please check your caps and grammar before sending so we do not have to do it.  Our time per day is very limited.>

Skimmer Choices/Selection – 12/01/06
Hi all,
<<Howdy Tim>>
I'm planning on a 75g reef tank with SPS, LPS, and maybe a clam with perhaps 8 fish.  I'm having difficulty picking a skimmer that would best serve my needs.
<<Hmm, should be pretty simple...choose a reputable brand/manufacturer and follow their recommendations>>
One of my fears is that I need a skimmer which is $600+ (Euro-Reef, H&S etc.).
<<Debatable for sure...but the high-end skimmers really do perform better/give more value for money in my experience/opinion>>
Do you think this is a likely scenario or will an AquaC or less expensive skimmer be adequate?
<<I consider AquaC to be one of the better choices in skimmer selection...very good quality/customer service...an AquaC skimmer would be a fine selection>>
In addition, what is the difference between a recirculating skimmer and a non-recirculating?
<<A recirculating skimmer is generally "gravity fed" from the display tank and the pump then pulls water from/returns water too the skimmer body in a "recirculating" fashion.  A non-recirculating skimmer generally feeds water to the skimmer body through the pump from an outside source (sump)>>
And is one superior to the other.
<<The recirculating skimmers are considered by many to be superior in performance (all things being equal), but that’s not to mean the non-recirculating skimmers aren’t excellent choices as well>>
Thank You, Tim
<<Quite welcome.  EricR>>

Re: Quarantine Tank Size -- Now, a follow-up   11/24/06
Hi Bob!,
<Hey Q, JustinN with you today>
More of a comment here than a question (though I will sneak a question in towards the end!)
<Hehe, ok>
Following the advice and good reviews on this site, I replaced my Red Sea Prizm protein skimmer with an AquaC Remora.
<An excellent decision, IMO>
I received the unit about 1 week ago, gave it a quick cleaning with warm water and set it into my tank.  I was a little nervous at first because the unit was not producing any skimmate at all.  The bubbles didn't seem able to make it even half way up the neck of the collection box...  Having read (here) that these units require a "break-in" period, I shelved my concerns and sat back to wait.  
<Always a good idea with a new addition, equipment-wise>
After about the 3rd day of operation, the skimmer appeared to suddenly kick into action, producing a large volume of organic laden bubbles.  With some minor tweaking (I was very familiar with making tiny adjustments after my aggravating experience with the Prizm)
<I know this all too well, am awaiting the arrival of my Tunze DOC 9002 to replace my Prizm as well...>
I had the skimmer producing a nice dry foam that resulted in a good volume of dark skimmate... Much more than I'd ever seen from the Prizm.
<Excellent to hear>
Thank you for the great advice.
<Hehe, wish I could take credit for this one *grin*>
What do you think about the twice a week, small volume (5%) water change regime outlined in detail on your site?  because I've noticed that my fish seems to react positively to a water change, I was considering going with this 'system'.  Would you vacuum the substrate every water change?  (this is not covered in the article).  Will this be stressful to the fish?
q
<I agree wholeheartedly with the sentiment of twice weekly, lower percentage water changes. I utilize a 3-4 gallon water change, twice a week in my 40 gallon aquarium. Usually, I don't disturb the sand bed unless there's a need. Instead, I use a small powerhead for water change purposes. My storage container sits next to my aquarium, with the pump laying in the bottom for circulation. I attach aquarium tubing to the pump, then place the pump in my display. Using the hose and flow from the pump, I start by blasting my rockwork clean and getting the gunk into the water column. Next, I direct the water out of the tank into a bucket for disposal. Then I simply toss the pump back into the storage container, and return the water to the tank. I see no reason that this would be stressful to the fish. Hope this helps you out! -JustinN>
