I'm setting up a 60 gallon saltwater tank and adding a sump by cutting through the glass, before cutting I want to have a plan of action, and know the setup I plan on using is going to work well. I've seen a lot tanks with outtakes in one of the corners and the return in the opposite. I'm a sucker for symmetry and I'd love to put my outtake in the center of the tank and a return on each side. I think this could also help (or seriously hurt) water flow. For the returns they would be fed off the same pump with a Y somewhere on the way up. Has anyone seen or had a setup like this and was it benifital? I want to do right by my aquarium, I can get over my OCD if I need to! LoL
