So I'm at a loss on power head placement on my 180 gallon (6x2x2). I currently have about 1200 gph from my returns. I have 2 wp40s 1 wp25 and a tunze wavebox. I've read any where from 30-75 x tank volume for flow. Im keeping a mixed reef and don't know where or how much power my power heads should be at. I don't want to blast my corals away. Here is a pic of my new aquascape. Thanks
