I'm ordering a Supa Dupa Power Head from my lfs. I'm going to keep my UGF in my 52 gallon tank as I cant afford a biowheel at the moment. I'm going to run the one power head as I'm getting an extra strong one, and placed it on one tower situated in the middle of the tank. Not sure on the model details. I will post once I know. If I was to run this power head on reverse flow, would that still provide adequate biofiletration or should I keep it on the normal flow??
