Can you explain what you mean by a closed loop system? My intent is to make the tank viewable on both of the long sides without any clutter from attached pumps on those sides, so I only want the circulation pumps/returns on the ends if possible. If that means I can only have a tank that is 8 feet long, I'm ok with that, but I was seeing if I got bigger with pumps that are controllable. I've heard about the gyre pumps, but I haven't seen them in action. Do they work well below the water line or only near the surface?
