Gph?

joshso · 11/12/2007, 03:45 PM

I'm turning my 55 gallon into a sump for my new 125 gallon. Any reccomendations on water pumps. How much GPH should the pump be able to produce? I am assuming that I should choose one with 1" fittings instead of 3/4" for more flow, is that correct?

The return pumps will depend on the how much the overflow can handle.

my eheim 1260 has a 3/4" output and is pretty decent

Andrew has got the idea here, You need to find out what your drain size is BEFORE you think about return pumps.

I'd target 300-400 gph for that size tank, but I agree that checking the overflow size is a good first step.

I don't yet have an overflow for the tank. I am going to put internal overflows in both corners and drill holes for the overflow and return.

Sounds fine. There's a link to a calculator for overflow sizing on the home page.
