We're all set with our 40x20 rectangle, but I'm having a difficult time determining the optimal location for the skimmers and returns. Our PB is presenting multiple options for us, but he's being noncommittal about the best option, so I drew a picture for all the gurus to point me in the right direction. It's not drawn to scale, but it's a basic 40x20 rectangle with corner steps and a bench tied into the steps. Deep end with a couple of deep returns is on the opposite side from the steps/bench. Let me know which option provides the best circulation. Thanks!
