I have a standard 75g mixed tank with a couple clowns, softies, lps, and a monti. I've been playing with flow but can't get it "how I like" I guess you could say. I have a wp-25 facing direct from right to left side on w-1, s-1, and it's making a good wave. I also have a koralia 1400 that I took out, and my return is a Jaebo dc3000 (800gph running at about 85% so ~680gph). So all I have going is my wp25 and return. How do you have your 75g setup up and would you mind posting an image or drawing of your flow setup? Thanks!
