Looking to upgrade protein skimmers on my 150 gallon system. I have been reading reviews on the net trying to formulate the absolute best option as this is the last "planned" buy for a while. My tank currently is what I would consider medium bioload, but I would like to skim as if it were heavy. I run a sump and desire to have the skimmer in the sump (footprint is not a problem). Currently running a MRC2 with a Mag12 and want to explore my options, based on performance, electrical savings, noise and ease of cleaning. My current front runners are SWC, ATB and Magus but I would like to hear some local opinions and perhaps see yours in action to find the best of the best. If you have one of these thats listed or others I should consider tell my why I should buy a skimmer like yours! :thumbs:
