I read about the FX5 today and want one really bad. But........I have a 100 gallon planted tank and from what I read it really puts out some water. You think it could be tamed down without closing it's return valve some. Maybe three returns, spraybar, etc.
I have been using a Ocean Clear filter for over ten years. My pump may supply 300 gph
. Could use a little more movement in the tank.
