I need some help with my flow, just upgraded from a 24x24 and I was able to get that tank dialed in. This one is throwing me for a loop, I have 2 MP40 on the overflow side, both my returns are 3/4 loc with vca rfg on them pointed at my center island with sps, problem is to I go low or high with the mp40s , tried both and no matter what the corals on the sand get too much flow. If the heads are low they get direct blasted if the heads are high the water flow back to the return side across the bottom is too much, any ideas?
