I have a 2x2x2 65 gal with a 20 gal sump. The tank has fish, live rock, soft and sps coral. I would like input on my flow in the tank. Currently I have a Hydor wave maker with two 450 koralia powerheads mounted on the back wall about 8 inches from the surface and pointing toward the front. I also have purchased 2 koralia 1500 max pumps which seem to have two much flow. Any suggestions would be greatly appreciated. I also have a couple 800 gph constant flow in my possession
