return pump for 75G recommendations?

[914]

Hi all!

I've got a 75G w/ integral overflow box w / 2 1.5" PVC bulkheads thru the side of the tank. This is a home-built internal box w/ teeth, and the thru-fittings are near the about halfway to the bottom of the 8" tall box.

The question is... about how much will this return flow?

And therefore..... what size return pump? I want to stay away from Rios.....

Any specific recommendations as to type/brand of pump? This is in my apartment, so noise is an issue, and i'd love to avoid a chiller..

otoh, the under-tank space is limited, so if it's an external pump, plumbing may be an issue.

thanks!

Sen700 should do the work. It can be operated at either internal and external

Typically people look for something like 10x-15x turnover rate per hour into their sump from their return pump. Have you checked out http://www.reefs.org/library/pumps/ ?

I would reccomend the Oceanrunner 3500 made by aquamedic. I looked into the Sen/dolphin/quiet one and asked a number of people before I bought it. Im happy with my oceanrunner, seems to be built quite sturdy and runs like a champ.

We'll you've got some conflicting needs there But:

I would go with an iwaki if you at all can. They are a bit noiser than the the sen but they won't add heat to your tank like a sen will. If you ahve to add a fan to the tank because you add a sen the noise is a mute point.

I only recommended the Sen because he mentioned that he would prefer a internal pump due to lack of space and possible plumbing problems. Myself would chose a Sen for internal and a Iwaki for external.

we ended up with a Dolphin 900, since it can be internal or external mount, and fits (the short way) into a 10g tank.

Thanks again!
