What is the purpose of flow in my tank and do I need more???? I have a 55g FOWLR. It has a Bio-wheel 350 and a Maxi-jet 1200. Tank has about 40lbs or LR. Do I want the powerhead to agitate the surface of the water or to flow across the sand bed to throw around debris? I know I don't want dead spots but what is a dead spot really in a FOLWR? My HOB filter creates some flow on the surface and my powerhead is not positioned about 6 inches above the sand bed to try and create a "around the tank" current.... Do I truly need another powerhead?
