powerhead and return nozzle placement

doox00 · 03/28/2006, 09:26 PM

I added a 3rd powerhead into my tank tonight to get some more flow, it seems a 90g tank should have 3 or 4 from what others have. This is how I have them now, this fine, or should I move them around some more? I may add a 4th powerhead if need be.

The powerhead in the back right aims into the rock formation there, into a gap between a couple rocks and comes out the front side.

It's difficult to comment on it if we can't see the flow. The real only way to know if it's good or not in my opinion is to see if detrites are collecting anywhere on the bottom of the tank. If that's the case, you will want to rearrange the powerheads so you won't have any dead spots.
Flow wise you should be fine, even though you didn't list the flow rate of the powerheads.
