im going to be adding a fuge to my 90 gallon tank fairly soon and i was lookin for some feed back on my design. all comments are welcome. the tank im going to be using is a 30 gallon the first black box is my skimmer feed pump and the second is my return. the outlet for the skimmer will go into the main intake on the left. the long line is my heater cause i cant think of a place to stick it.
