Return pump, how big is too big (1 Viewer)

[Guest]

I have a 29G w/10G fuge. Today I upgraded from a ViaAqua 1300 (374gph) to a ViaAqua 2600 (740gph) as my return pump. Do you think that is overkill? The tank certainly seems to have huge flow now. Note I also have two Aquaclear 4000's (400gph) on alternating 15 minute cycles and a Powersweep 214 (160gph) sweeping the front of the tank.

AS long as the overflows handle it, and you can find places for your corals that prefer lower flow, the more the better. I have a Mag 7 (700 GPH) on my 29.

May have a bit of trouble finding low flow areas, but then again I am not exactly sure what represents low-flow. May have to split the return pipe into two outlets to spread the flow some. Is there a trick to locating low flow areas?

You can always split the reurn like you said. I always use my xenia as my flow indicator. If it can stand up its fine

I have a MAG 950 on my 115 FOWLR setup. The way I see it, you can never have too much flow. Get the largest return pump your wallet, and overflows (like Shane says) will allow.

I have a GRI 520 (1500 GPH I think) on a closed loop running on my newly-resetup 120 gal. It drives 2 3/4" sea swirls. The flow tends to blow around the sand at the bottom of the tank. I'm still not sure if this will be OK or if it is too much flow. . .

depend on what you keep.. some softies like bubble or pearl corals don't like strong flow. with sps the more flow the better as long as the flow doesn't blow directly at them.
