i am running two power heads in my 10g. one is a marine land 1140 and the other is a aquatic gardens 600. the 1140 is rated at 300 gph and the 600 is rated at 200gph. is this to much flow for my 10 gal.
I've read were people have 100x turnover and their tanks look good. I think as long as it's not causing a sandstorm, your okay.
