Tunze 9005 Space Requirements 2/23/08
Thanks for being out there and so very helpful.
<Happy to help, be a part of the site.>
I spent the last hour or so on your website and have learned a lot.
<Good.>
I still need to ask a question or so.
This is my first salt water tank venture so thanks for helping. I have a 70 gallon Oceanic reef ready tank with a 31"L x 15"H x 15"W refugium. This will be a FOWLR with some corals.
<This makes it a reef.>
I have about 75lbs live rock and 40lbs live sand. There are many snails and crabs and about 7 starter fish. Water is pumped with a Little Giant
1400gph. I was looking at the Tunze 9005 to add. I need to fit it into a 5" x 10" compartment in the refugium. The water will be about 13" high.. Will the Tunze 9005 fit and work efficiently in this area?
<It will fit, albeit snugly. As far as efficiency, just be sure it gets raw water to that compartment from the overflow.>
Is there a better item for this specific compartment size?
<An AquaC Urchin should fit in this space also. Either skimmer will do a fine job for your tank. Happy reefing, Scott V.>

Tunze 9010 For A 200g Reef? – 01/15/08
Hi,
<<Hello Marcus>>
I have just setup up a new 4 x 4 x 2 reef, upgraded from a 4 x 18” x 2.
<<Neat!>>
I am using my skimmer from my last tank which is a<<Tunze>> 9010, which I was pretty happy with.
<<I too like Tunze skimmers>>
I am copping a fair bit of flack in my build thread about how undersized this skimmer is for a 200g reef.
<<Really? Hmm, even though your new tank specs out at about 239-gallons (actual true “empty” volume depends on the thickness of the panel material)…the Tunze 9010 has a “usage” rating of up to 264-gallons>>
What is your opinion?
<<I saw many of the “classic” Tunze skimmers in action overseas years back, and well before similar quality skimmers were available in the States...they were awesome. I don’t have any direct experience with the new Comline skimmers like the 9010, but have heard positive comments from others… I suspect you/this skimmer will be fine>>
Should I consider upgrading?
<<Is up to you, but I would probably wait to see how this skimmer performs with the new system>>
I am only stocking with a medium to light load of LPSs/sps and fish, with a pretty open aquascaping.
<<Still…best to plan/install filtration components for a “heavy” load, in my opinion. Even when we plan for/know better…we sometimes can’t help adding “just one more fish”>>
If I upgraded to a 9015 or even the foaming cup for the 9020, how much of a difference would this make, given that, other than the collection cup and chamber height, the skimmers are exactly the same?
<<Hmm, the 9020 is a “double” unit, though the 9015 does appear to be identical (air/water flow specifications) to the 9010 but for the size of the collection cup…which may indicate the smaller unit is just as efficient on larger tanks (i.e. – can handle the same “bio-load”) but is limited by the amount of skimmate it can process/hold before needing attention. In other words…if you’re willing to empty the cup more often, the 9010 should serve as well as the higher capacity-rated 9015 on larger systems>>
Many thanks,
Marcus
<<I do think your Tunze 9010 will serve your new system…but, give it a try first and see what “you” think…you can always upgrade or add a second skimmer at a later date if necessary. Regards, EricR>>

Protein Skimmers: Bigger is Better?  12/16/07
Hi Bob and Crew,
<Scott F. your Crew Member today!>
Thanks for all your previous help and advice.
<You can't imagine how much fun it is to be of service to our fellow hobbyists! We have some amazing people here and we love this stuff!>
As before, I am in the process of setting up a 850L (690L Cleair tank 160L sump) mixed fish and invert system. I have very limited headroom in the sump area max 50cm. After a lot of searching I have found what I believe to be a potentially ideal skimmer. Tunze DOC comline 9010.
<Fine product from an excellent manufacturer!>
My question is, do you feel that this is a good choice for my water volume or would you lean towards the 9015. In the future, I would like to invest in MH lighting to allow me to add coral (currently not an option with all the other new stuff I have to purchase). With this in mind, and notices on the Tunze site about running bigger skimmers for reef systems, I would rather invest in a system that will cover my future needs. Thanks and Regards
Steve
<Well, Steve, I am of the mindset that "bigger is generally better" when it comes to skimmers! This philosophy does not always work with other things ("bigger" chocolate soufflés, large bottles of sauerkraut, "deluxe" carry on luggage, etc!), but it generally works with skimmers (as long as you don't go overboard), IMO. I like the 9010, but if you plan on a heavily stocked reef system in the future, the extra capacity of the 9015 will justify the additional expense, IMO. Tunze products are fantastic, and I use a number of them on my system with great results. Hope this helps! Regards, Scott F.>

Tunze Nano Skimmer Noise And Its Effect On The Fishes? – 07/17/07
Dear Wet Web Media,
<<Hello!>>
First off, thanks so much for taking the time to answer questions and post them.
<<Is our pleasure...>>
Even if you don’t have time to get to mine, your responses to other hobbyists’ questions have been invaluable.
<<Thank you for the kind words...and fear not, we “will” get to yours (hey wait!...I’m doing that right now! [grin])>>
I actually bought the Tunze Nano DOC protein skimmer based on the information on your website.
<<I “do like” the Tunze products>>
I have a 36-gallon All-Glass bow-front tank with a Penguin Bio-Wheel 50 filter and the Tunze Nano skimmer.
<<I see>>
It’s going to be a fish-only tank with lots of live rock and live sand.
<<Cool!>>
I am definitely a novice so please forgive the likely stupidity of some of these questions.
<<Mmm...consider yourself “thumped” on your forehead [grin]>>
I have some issues with the Tunze Nano, probably due to my own inexperience more than anything else.
<<Do visit the Tunze forum on RC...I’m confident Roger can help>>
1) The Nano is really loud. I have it submerged to the proper water line in the tank and it is upright as required by the instructions. I thought it would be a lot quieter. Should I raise the water level?
<<Worth a try>>
Anything I can do to decrease the noise?
<<You might try “backing off” the water jet a bit...but do give Roger a shout and see what he suggests>>
2) There are no fish in the tank yet, just live rock and live sand. So far the Nano cup has just collected water.
<<This may be all there is to “collect” at the moment. It may also be an indicator the skimmer is not yet “tuned” correctly and possibly the reason for the excessive noise>>
I can see white foam bubbling in the inner compartment though. It’s been running about 5 days. Is this normal?
<<Hard to say...>>
Should I empty the water from the cup and increase the air?
<<Experimenting with both the air and the water inputs is a good idea and will likely improve performance and maybe even resolve your noise issue>>
3) Now here’s my really silly question
<<I’m poised to thump...>>
If I put my ear to the tank, the Nano is even louder, which makes sense since the entire mechanical operation is taking place in the tank.
<<Mmm, yes...the vibrations travel quite well>>
My question is, does this noise bother fish?
<<I don’t believe so, no... One thing I noticed since beginning diving is the underwater environment is anything “but” quiet. Even though the noises in the tank may not be “familiar” at first, I do think the fishes become accustomed to these...much the way we become accustomed to noises in our home/workplace>>
Have there been any signs of stress in marine fish due to noise level? (I know it might seem silly but I want to provide a proper habitat in every respect that I can).
<<Not that I’m aware of...and not silly at all, mate>>
Anyway, thanks a million for looking at this, I really, really appreciate it!!!
<<Happy to assist>>
Cheers,
Lauren

Just wanted to say thank you, thank you, thank you.
<<You are quite welcome, welcome, welcome!>>
With your help, my nano and I have worked out our issues and are getting along swimmingly.
<<Ah, very good to hear (or "not" in this case [grin])>>
Thanks for running this site - it's fantastic. =)
A collective effort…we’re pleased you like/have benefited from it
