This is probably the worst drawing I've ever done lol. But I'm trying here lol.

Just for this stupid app for the iPhone just for you. You should be honored cause I almost threw my iPhone out the window lol.
Stock intake up and angle as far right as you can. Now the power head. Up high and pointed upwards to create surface agitation and directed towards the front middle of the tank.
Hope this helps. If not I'm short of coming there and just doing it myself lol.
This drawing made my day, love it. Stock intake is the current flow head right? Also am I looking straight down on your drawing? Still confused as if it is LEFT SIDE meaning looking at my tank straight on, is it the left SIDE or back wall on left side?
