MY wording should have been more clear. Either way, I get much more effective debris control now with this setup. If I put flakes in my tank now, they are beyond halfway within a few seconds, it really keeps the tank much cleaner. As stated earlier, Ill get a before and after pic up for you all to take a gander at. I think the majority of the problem with the dual nozzle output, is it was designed with the intention of placement int he middle tank, creating dual swirling currents. I have mine in the corner, so I just wanted one big circular current in the tank, and removing the dual nozzle definitely gave me my bang for my buck.
