I am planning a closed loop manifold to go around the top perimeter of the tank for my sole circulation/flow for the whole main tank. I want to power the manifold by using the sump return pump and the closed loop (not to be confused with the closed loop manifold) pump. The benefit that I see is with the manifold I can direct flow to many different areas of the tank and have no poweheads or other plumbing inside the main tank.
