I was interested in either a swc 160 cone or a 180 cone. After reading alot of threads it seems that the reef octopus pump might be better and just as quiet as an swc skimmer? Noise level is very important. Which reef octopus skimmers, doesnt have to be a cone, would you recommend for a moderately stocked 90 or 120. Ive read thru tons of threads and have forgotten most of the stuff so now Im back to ground zero with a headache to boot.
