I pretty much have the same setup as bckane but I have a 46g tank. I bought a 20 gallon glass tank and an H.O.T overflow and I was thinking of putting my Romara aqua C in the sump area as well. I'd remove the prefilter box and extend the intake tube for the MJ1200 PH
that feeds the skimmer so it's lower in the sump .
Gatorfreak - how can you quiet down the water fall affect and noise that would be coming out of the skimmer because I think you would be right, the water level would be lower than if it hung on the tank it self.
