Water pump sel. 4/10/09 Re: Water pump 4/10/09 Increase in Pump Size? 10/15/06 Greetings Bob & Crew
<Greetings.> Got a question for you. In my 125 reef with 40 sump,
I need to replace my return pump. It is a QuietOne 3000. It has
performed flawlessly for over 3 years now. <I am amazed.> Lately,
it has jammed by itself several times requiring a disassembly and
reassembly to restart. Equipment/Pump Selection Quiet one 4000 vs. Mag 9.5 4/21/06 Hello crew, <Hello Anthony> It's been a while since I wrote - hope everything is well. <As good as it gets.> Anyway, I have a 75 gal tank with a 20 gal sump and a Mag 7 return pump passing through an Arctica 1/10 hp chiller. It seems that the output from my Sea-Swirl is less than the output from my Maxi-Jet 900 power head (230gph). I think that the chiller is the major bottle neck. <More than likely.> I'm planning to get a stronger return pump but can't decide between a Quiet One 4000 (50watts) or a Mag 9.5 (90 watts) with similar gph. I like the Quiet One for it's size and low wattage but concerned about the noise level some users are complaining about. (I want it at least close to the noise level of my mag 7) I also like it because there's a dial to control the flow rate. There are also complaints about re-starting the Quiet One. Are these concerns valid and is the Quiet One really quieter than the mag drives? <Yes, they are valid. Most people want to keep noise to a minimum if possible and conserve on electricity. If it were my choice I'd go with the Quiet One. It runs about 20 watts less giving you very close to the same flow rate and head pressure. I think they are a quieter pump than the Mags and I've never heard any complaints about the new models. Thanks, <You're welcome. James (Salty Dog)> Anthony Quiet Return Pumps? - 04/23/06 Good Morning WetWebians; <<Late night here on the East Coast now...Howdy!>> I apologize, as this is a little long, but here goes. <<No worries mate>> I am in the process of sorting out the plumbing for a 6',180gal. reef. What I have for plumbing are two overflows, each with a 1.5-inch drain which dumps into a Rubbermaid container in the stand beneath. I think these are good for about 1200 or1300 gph each. <<Mmm, yes...on paper. Can take much fiddling/tuning to get this much out of them>> From there, a 1" bulkhead feeds a Quiet One 6000 which pumps the water back to the tank through, perhaps, four feet of 1" PVC (with two 90s and one 45 elbow), at the end of which will be a manifold of some sort. <<Ahh ok, good...you're not trying to "max out" the overflows through the sump (yet)>> Also on the Rubbermaid, is a 1.5" bulkhead which will drain to a 75gal. sump/refugium in the basement (currently, there is a 35 gal. tank there, since I am using the 75 to hold my livestock in the interim). The return pump will likely be a Mag 24 to go back to the display tank (there should be about 13' of head) and then a SCWD. Both returns are through the overflows via 1" bulkheads. <<Okay...trying to get my head around this. You have two 1.5" drains going in to sump #1, which then drains through a single 1.5" throughput to sump #2. Sump #1 returns water to the tank via the Quiet One 6000 pump, and sump #2 returns water to the tank via a MagDrive pump. I think this is a balancing act that will end in disaster sooner or later. Do reconsider having sump #2 return water back to sump #1 rather than back to the tank. This way you need only work with "one" pump to set water flow/primary sump levels. It will be impossible to balance the two pumps to each other on a continuing basis>> I chose to use the Rubbermaid as an "intermediate" sump so that I could use an external pump as a main circulator (heat issues with submersibles) without having to drill my 75. <<Should be fine>> It also allows for a short return path on one pump while allowing the versatility of a basement sump. <<Do think about my previous comments re>> I have filled the system with tap water and am testing using a Mag 9.5 in the basement sump for now, and the aforementioned Quiet One 6000, and have been playing around with Durso/Stedman type standpipes to quiet things down. It looks like things should work out except, the Pentair pump is pretty far from being QUIET and will have to be replaced since it is far too noisy in my living room. <<Yes, have heard this before about this/these pumps>> I have contacted Pentair in this regard and am waiting to hear back but, alas, I think I will have to get a different pump. <<Agreed>> So, after finding a few reviews, I am considering a Pan World 200PS (which I think is the same, more or less, as the Blue Line HD70). <<Yes>> They seem to be sort of a knock-off of an Iwaki, only quieter (but quiet enough?) and more affordable. <<Not "seem to be"...is... Though neither stands up to a "Japanese motored" Iwaki in my opinion. I have seen Japanese motored Iwaki 100s that you almost had to put your hand on to determine they were running. But that said, I know reefers who swear by the Pan World and Blue Line pumps...though I think just about anything is going to be "noticeable" in your living room...to some degree>> Does anyone there have an opinion on this pump or have suggestions on another 'in-stand/in-the-living room pump'? <<GRI (Gorman-Rupp Industries) produces "relatively" quiet and powerful pumps of good quality. The GRI-520 would be a good replacement for the Quiet One 6000. But the Pan World/Blue Line are cheaper (quality and price) alternatives>> I've looked at some reviews for Gen-x/Mak which suggest they are loud, and the Dolphins seem too big. <<Agreed>> Poseidon is rated as almost silent but may not be big enough. Sequence may also be an option, but are these last two magnetic drive? <<Direct drive I believe...and though quiet (or quieter, maybe), I have heard of heat problems with these last two pumps>> Is direct-drive inherently quieter than magnetic drive? <<No...but should handle head pressure better>> Would this present a problem with salt creep through the seals? <<Would depend on the quality of the pump I think, but if designed for saltwater use...probably not>> It's a lot of questions, I know, but I am not really sure how quiet I can expect a pump to be, since my last reef used powerheads for circulation and I don't have experience with external pumps other than the unfortunate not-so-Quiet One 6000. <<Understood...I had the same problem when I built my in-wall display in my living room. I ended up opting for a smallish submerged model return pump (Mag 12), and am utilizing Tunze Stream pumps for circulation. The couple degrees temp increase from the submerged pumps can usually be handled quite easily with small fans positioned to blow across the surface of the water in your tank/sumps...and 12v "computer" fans are virtually silent>> Thank You For Any Insight You Can Provide; <<I hope it has been helpful, EricR>> John T. P.S.: If you think this is an expensive hobby, I live on the Canadian side of Lake Ontario. Prices from suppliers up here are nearly double what they are in the U.S. <<Yes, have heard this>> And, Big Als won't take the Quiet One back, so I'll have to E-Bay it, in which case, "it's a great pump and anyone would be happy with it!" <<Mmm, buyer beware indeed! Regards, EricR>> Inline pump questions 1/16/06 Hello again Crew-
<Hello Brent> I want to upgrade my current Pondmaster Mag-Drive
Model 7 unit (700 GPH) with a Pan World 100PX-X
(1270GPH). Details for what I want to setup are
below. Is there a difference in the amount of heat
transferred to the water between these two pumps? <Not familiar with
the Pan World.> Pump recommendation Hello all and thank you
for the great site you have. I am a regular visitor and have used your
site for a lot of my decision. I am wanting to see what you would
suggest for me to get. I currently have a POS CA pump that I am using
for my return from my sump. This unit does not move anywhere near
enough water and has problems starting back up after it is turned off
for any reason.
