I have a 60 gal tank with a 500 Gph and a 750 Gph pump at each end. The pumps are mounted about 6 inches below the water line at opposite ends of the back wall and are directed slightly down and pointed so they hit the front about 1/3 from each end. There is a dead spot under the 750 where a patch of cyano grows on the sand bed and a crater in the sand up front where the flows come together. Are there any rules for this? I don't want to keep moving them around and disrupting the sand bed.
