Hello all. I have 50gl. tank that I want to put a sump underneath. I have a small tank that I'm going to use for the sump. I want to put some deviders in it so can can have a small fuge it. I need some help designing it. The sump tank measurments are 12" wide x 16.5" tall x 29.5" long. I'd like to have what i think are called over unders to help with bubble control. If any one can hep with how high and how deep these should be it would be greatly appriciated.
