I've been searching for the last couple days, Ive found that mag drives leak, and Pentair Quiet One, are not so quiet... but what i have not found, is quality suggestions.

Specs-
around 500gph +/- 100gph
external / in-line
quiet
quality -won't leak
under $100

Thanks
Jim

I have been wondering about the same thing,I even bought a GEN X 6000,it's way too loud,I've heard people saying good things about "poseidon pumps(expensive) and how quiet they are.
I think we should expect pumps over 800 GPH to be slightly noisy .

Guess I'll find out soon. I ordered a couple Quiet One 4000 pumps since a few here recommended them and said they were fairly quiet. If they're noisy they will have to go. Well at least if I can get another quieter pump reasonably priced.

The Poseidon pumps are apparently the same as Blueline Velocity pumps. If you go to any of the reef sites, you'll find plenty of comments on them. I got one of the Velocity pumps from Champion Lighting & Supply. I can vouch for it moving a lot of water and for it being dead silent. It gets pretty hot, however, and can heat even a large tank to over 80 degrees.

I own two Velocity T4. Like dipan said, it is dead quiet. One is an old Custom Sealife on a 155g reef. Been running since 2000. The other one, Blueline, has been running nonstop since 2003 on my 90g reef. It is a little bit hot but I would not expect someone to use this in a small tank. I used to have a Mag12 on the 90g Reef and the temp was the same. They move a lot of water.

PanWorld and Iwaki pumps are both great picks as well. I use a PanWorld as the sump circulation pump on my reef tank.

What about an Eheim hobby pump? I've heard good things about it (and I'm about ready to set one up in my tank).

I think a 1250 may fit your needs?

Eheim pumps are also top notch. I don't run any external but they can be used that way as well. Dead silent.

If only they had bigger ones available, IMO even the 1250 isnt sufficient for large tanks.

 

[jpfelix]

ampmaster pumps are an excellent choice as well.

The largest available is the 1262.


If you really need flow, do what we do in saltwater, Sequence circulation pumps on a closed loop, or Tunze powerheads. Neither is cheap of course :icon_frow

 

[crazy loaches]

Yeah, I meant the 1262, just had the 1250 in my head since it was mentioned. As I recall the 1262 is rated about the same GPH as the QO4000 at about 6 foot head and are over double the price. I've been told ocean runners were also good when I was looking, but ended up getting the QO. Will see how loud they are in a couple months when I got everything setup.

I use a Mag 500 externally. It doesn't leak, but it does give off some heat. Where are your mags leaking? If it's the threads, you just need a bit of teflon tape. If not, either you got a dud, or I got the best one .

I've run eheims externally too. Not as powerful as Mags, but they come ready-made for tubing. If you don't need a ton of push, eheims are darn nice. Otherwise, I still say Mags are the best bang for the buck.
