I have 20G Tall with one Hagen 20 (125Gph) power head. Is that enough water movement? I have FOWLR and few Corals and would like to add more corals. Someone suggested that it wasn't. So, if I was to add another one (first of all, would that be enought WM?), where should I place the power heads? Thanks!
