What would be the best skimmer for a 120 with 30 sump sps dominant with heavy load of fish? I was just looking at the new 9420 but its a bit out of my money range. Was wondering if the classic doc skimmer 9210 would work stand alone, or even the doc 9015? Also, how are the tunze skimmers compared to the other skimmers out there with similar tank ratings? What makes them so special?
