My tank is 40 gallon, 4 inch sanbed, 50 lbs of live rock. I'm having very much trouble with powerheads.
I'm thinkin of 1 in each of the back corners but how many GPH?
I kinda want one that will rotate 90 degrees back and forth? (in the corner) Or do those cost too much ... or can all power heads do this?... or is the rotation just unnecesary (i got the idea when i saw it at the lfs)..
