I want to use sand as a substrate in my 90 gallon. I'm trying to decide between PFS, eco complete or just some plain old silica sand. My question is how do I use a powerhead for water movement without destroying my filters. I wanted to use the powerhead to blow the waste and leftover food particles around so that the filters can do their job better. If I have to put sponges on all the intakes doesn't that defeat the purpose of getting rid of the solid waste.

Thanks in advance

My purpose in using the powerhead is to get flow along the substrate surface. Anybody with sand have a powerhead going across the lower portion of the tank rather than the upper surface.
