I need a Quiet pump

[Zoos]

Hey guys I am in the process of building a new tank, it will be a 125g cube (38x38x20h) I am looking a for a return pump, the catch is, that it has to be quiet. I mean super quiet, it will be in my room where I sleep! if anyone out there can help in any way shape or form please do so, if you can compare what you have to offer with say a little giant 4md, because that is pretty much all I have heard, and can use it as a reference for comparison. thanks

what type of rate are you looking for on your circulation. I have used the iwaki pumps and they are quiet and I have also used the pan world pumps and they are quiet. I have the 40 px and it is way quieter than the giant pumps I heard if you move up to the 50 px it get's a little noisier. (premium aquatics)

If you have the space you can run a blueline. Very quiet and not that bad on electricity. I have a Quiet One and its super quiet. Others say they arent. Just decide what GPH you need and go from there.

I love Quiet One pumps, I have 3 and they are all quiet run externally and internally. Some have had problems with them, but what man made product doesnt have its issues sometimes.
They arent real expensive, and do a hell of a job.

Here is a link to the pumps, they have good flow numbers and I feel they would be perfect for the flow rate you want or need and they are very durable.
Plus they are on sale now.http://www.drsfostersmith.com/Produc...547&in_merch=1

I forgot heat is also an issue a big issue as I am in Miami, and will not be running a chiller, and will be using MH and VHO's, I am aware of the quite one pumps, but they are only quite when you stay in the 6000 model and below the larger ones I have heard and are pretty noisy. also when you run them external they are not as quite. (I have a 4000 on my current tank) and as far as how much flow I was looking for something compatible to the little giant 4MDQX but (about 1300-1400gph). as far as the iwakis and the pan worlds would you say those are the quietest pumps on the market as far as inline external pumps? also are they reliable, do they emit a lot of heat? and where is the cheapest place to buy them?

[Blown 346]

For the 1300-1400 GPH hour range the Quiet One 6000 will do 1506. Or is the 1300-1400 GPH what you want after head loss.
My quiet one pumps run cool, I am not familiar with any other pumps since the Quiet One pumps arethe only ones I use.

[Zoos]

yes I want 1300 after head loss.
any experiences with velocity or sequence pumps?

A lot of people like the sequence pumps but I have no experience with them.

If heat wasn't an issues I'd day velocity T4. If your flow was lower I'd Eheim. I suppose Ocean Runner is a possibility, but in this instance I personally would very strongly recommend the Aqua Sea 2100.

It's not the cheapest but I think it's the best. Just be sure NOT to get the one intended for freshwater ponds... the Aqua Sea line comes with "the best marine seals, grounded electrical cords, split nut pump union fittings, and are backed by a one year warranty plus a nine year factory service guarantee."

This was previously know as "ampmasters" line of pumps, you can see the curve and amp draw below, but the key with this pump is it can be dialed back to a desired flow rate without harm to the pump:

I should also mention I have a Gen-X PCX-40 (Mak4) and it's terribly loud:

Unless you need the pressure rated flow and low cost I'd avoide it. I'm about to take it apart again to see if I can find anything wronge, but as far as I know it's always been this loud.

[Zoos]

so the aqua sea is a dolphin pump?

so eheims are quiet?

[sjm817]

Too much display->sump flow and a desire for a quiet system are a tough combo. There is no need for that much display-> sump flow. I'd cut that WAY back and put the flow where it is needed. In the display.

[Zoos]

Hey I'm all for a closed loop, I still need help deciding what pump to get, I can simply us my quiet one 4000 for the display and use the big pump for a closed loop.
still open for suggestions

[Zoos]

Another question, will i use a pressure pump for a closed loop or a regular pump for circulation? i am considering the iwakis, is there a major difference between the american and the jap motors?

anyone?

For what it's worth I run about 600GPH on the return, and 1000 GPH with my pressure rated PCX-40 on a 2 port closed loop with Eductors. I don't love it, it's just what I have on hand.

As an earlier poster stated it's easy to get a very quite return pump if your fexible on the flow, and yes Eheim pumps are and have been famous for their reliability and low noise. The only thing I can assure you is almost silent is the Velocity line, but they *will* add heat:

I've heard japanese iwakis built a very good reputation over the years. I find there larger pumps quite loud but have very little experience with them, from a stats perspective I think there are better options now. This is particuarlly true because a pressure pump may not be necessary for the setup you've described (pressure seem to equal more noise).

Any pump recomendations are related to what your going to keep in the tank. Without knowing I'd say look into a Sequence Dart or Aqua Sea 2700, 3000, 3600 pumps for a closed loop. People seem to like those, particualrly the Darts.

[Billionzz]

The Quiet One are quiet and work well but thety have a flaw.

When the pump goes off it doesn't restart by itself every time, so if you need this pump for a sump I would choose another pump.

I have had 4 or 5 and they all did the same thing, but they are very quiet.

i forgot to mention it will be an sps tank

I had a tank in my bedroom once - literally like 2 feet from my head, so noise was a concern for me too.

Here's my take on this: a lot of pumps are hit and miss for noise. Some people say Iwakis are quiet, and a LOT of people say they are noisy.

Personally, I got a Queit One 4000 HH, and found it was the absolute noisiest piece of junk on the planet. A lot of people say they are dead quiet, but mine was not. (Not even close.)

People have said Eheims are quiet. I just got one (a 1060 - 600gph) and it still had a distinct hum when I plugged it in. Not super-loud, maybe a little quieter than a Mag 7. Maybe it just needed to settle in - I only tried it in a bucket of water for maybe 10 seconds.

Here's my vote: get a Velocity pump. I have never heard anyone say they are loud. I got got one, and yes, they are completely silent. (I had the T4.) I have not really heard otherwise, so for me, consistency wins out over hit-or-miss pumps in terms of noise. You can also add a small fan blowing on the pump it self - that seemed to help control temps for me.

Otherwise, I have not used a Sequence, but I hear they are pretty quiet too. Can't vouch for them though.

Yeah i'm pretty sure that the velocity is the quites pump out there, i also have access to the old external quiet one pumps, it is the same as the velocity, they are water cooled. i'm just really worried about the heat i wonder how much heat a t4 would add to my tank? even with a fan. i'm just avoiding having to buy a chiller, that and the chiller makes noise too, so i'm between a rock and a hard place. i will look into the velocity pumps, maybe even contact the manufacture, and see what they have to say.
thanks though.

I had my T4 on a 60g cube, and with a fan, I was able to keep my temps at or below 83F. It usually hovered right at 82 day and night. But then again, I also had a 400w MH in an almost completely enclosed canopy. It all depends on your setup - I'm sure if you add enough fans - maybe one in the sump too - you could get away without a chiller.

Look on the bright side - you won't even need to use a heater. (I'm serious too - for me, its just one more thing that can go wrong...)

[Zoos]

lol i guess, it is a bright side, but my house gets very cold at night so the heater is not optional. are you familiar with the panworld pumps? are they really quieter and run cooler than the iwakis?

My tank was in the basement, with the stand sitting right on the concrete floor. (Yes, my bedroom had a bare concrete floor - after a few aquarium 'mishaps' ) And my dad was too cheap to buy a new furnace after we added onto our house, so our current one was WAY underpowered - so yeah, I know what you mean about cold nights. But you'd be surpirsed how slowly some tanks shed heat - especially if its gonna be acrliyc.

But anyway, no, I've never used panworld/blueline or iwaki. I have heard the PW ones are slighly better, but I wouldn't trust a big pressure rated pump to be all that quiet regardless. If even one person says they're loud, (which they have), then Murphy's law dictates that I too will get a loud one.

I'm looking into Gorman Rupp Industires pumps though, they look pretty good. I started a thread about them over here:
