Jay, great job. So you basically just cut off the plastic mold and glued the dumas prop on? So in your opinion is it a lot more flow? I have one eco and one sureflow in my 125g in opposite ends on opposite sides and i have to say, i don't think i want 2500gph blowing in my tank, there 's almost to much turbulence in my tank now. Around 4000gph right now and i think thats good. But a video would be cool. And thanks for the pics.
