In my 29 gallon setup I run a UGF, an Aquaclear 200, and a Tetra Whisper 30. The water moves pretty well but it doesn't seem excessive. Of course excessive is a relative term. Does anyone have an opinion as to whether this is too much current for an angelfish to be happy? I'm thinking of adding a Penguin 100 gph biowheel when I take out the UGF. That would add more current.
