I think I need to redo my water flow pattern. I have a couple of dead spots and slight debris buildup on my LR. Right now its a 75 FOWLR working its way to a reef. I have a MJ1200, seio 620, magnum 350, and out-take from the sump to develop current. Any suggestions on placement would be helpful. Also, not too sure if I should have flow directly on the rock or around it. I am trying to create more turbulent flow as opposed to laminar. Thanks!!!
