power head setup ?

[peasly1]

is there a pic or diagram for suggestions to set up ph's in a 125 gal..how many what size where to put them...I think I am getting to much current,sometimes getting little sand storms and it covers the lr,and I've move them around a couple times,I have 3 plus 2 fuvals, and want something to compare too.. thanx

I have all my power heads in my 180 at the top of the tank. I use them to ripple the top of the water and also provide some current for my corals. Some power heads have controls to turn down the flow. You can do this or, put a prefilter on the power head. That will limit the flow a little.
There is no one way to do it. Just put them the way you like and aim them up a little.
