Where is the best place to put my vortec pumps? I have a 90gal with one upper front right side of tank and the other mid level mid left side. The Right pump is the master and the left is the slave. I have it set on reef crest but I am not getting a good reef wave. The overflow is back left side of the tank with the 2 water return facing to the right, one straight to the right side and the other angled to the front right. I aam not getting any pooling but I am sure ther is a better way to set it up. Any info would be helpful
