Looking to change out my SCA-301 protein skimmer on my 45 gallon reef. Not loving this skimmer, performance is ok and its LOUD. Looking for replacement suggestions. The tank will be heavily stocked with SPS. Only major drawback is my sump, need something less the 6" wide. I looked at NYOS and RLSS skimmers, not sure if there is something better out there. All suggestion appreciated!
