building a sump and I purchased a SRO protein skimmer. It say optimal depth is 5.5 inches. if I put my skimmer in first chamber and the first wall is only 5.5 inches then wouldnt the entire sump water level be 5.5 inches? The return chamber would be pretty low or is there a way to make the return chamber have a higher water level than the skimmer? Or can the skimmer be in depeer water more than 5.5 inches? thanks for any help
