What is the suggested placement for powerheads in the tank. I have a 75 with two powerfilters, one on each side of the back wall, 2 aquaclear 70 powerheads, one on each side wall and one 50 in the center. The center one is above my heater and is pumping down. The two on the sides point towards the front of the tank and I notice the fish stay towards the bottom of the tank unless I turn the units off, then they use the whole tank. I am wondering if I should lower one or both the side wall mounted powerheads to the bottom of the tank, but if I do the flow from the head would blow away everything around it.
