I don't believe that at all.......I have no returns above the water cause I don't like the sound of it......and I have never had scum on the water top......If your gonna go with a sump then all you need us enough water turn over to keep them scum away from the surface.....so in other words take the size of you water volume...Multiply it by 4 or 5 and that's how much turn over you will need!!!
