I will be building a 45 gallon sump for my 125 in the next month. Does anyone have a good link for building a wet/dry specifically for freshwater. Does anyone know what size pump I should be using? The 125 is predrilled with 2 overflows. Lift with cabinet will be about 4-5 feet. I was thinking of using a small sump pump that I have laying around. I will have to check the output but I believe it is rated at about 1100 gph. Would this be too much?
