It's not just the surface agitation that I'd be interested in increasing but the overall flow pattern. With the current setup, it looks like you basically have two currents pointing to the middle of the tank from above. This will probably create 2 circular flow patterns - clockwise on the left and counter clockwise on the right. Which is alright, don't get me wrong. I just thought that if you directed one of the powerheads on the right to a different position, it would create a more random flow pattern throughout the tank which would help keep detritus suspended in the water column so that the skimmer can get it out. Just a thought :idea:ionracing said:i have been playing with that one for awhile.........the skimmer and overflow box create a nice ripple on the top.............so i wasnt sure if its enough................plus with the skimmer, overflow, wet/dry.............the water is tumbling lot....................????????????
