I have a fluval 204 in my 35 gallon hex. Due to the relative power of the fluval and the relatively small surface area of the hex tank, the output agitates pretty much the entire surface, even though I run the output about 2.5" BELOW the water surface. When I dump in food (be it flake, frozen bloodworms, or frozen brine shrimp, the fluval drives the food down pretty quickly. Is there any way around this problem with the small surface area I'm dealing with?
