Placement of power heads??

Maybe this article will help you decide:

You could use the 4 to generate alternating directional flow, 2 at a time. What intervals does the Wavemaster support? I'd think that with 2x1600 gph (or whatever the modded 1200's are rated) would work just fine, with two in oppostion for the alternate pattern.

Thanks all. I am going to try them in a couple of positions and see how it goes. These powerheads have a lot more flow and I will be watching how much sand gets kicked up. Will be watching corals and anemones too...
