[I'm starting a 10 gallon reef tank and need some advice on water circulation. I tried re-using an old powerhead to help push around the water (planning ahead for the corals), but.... It was like watching a hurricane hit the tank (WAY too much pressure against the sand.)
So... I need to replace it. I'm assuming something in the 70-100 gph range, but that's just a guess.
Advice?]
