Curious as to how large of a tank these skimmers can actually handle with some efficiency. I currently run one on a 56 gal FOWLR. It has the mag 3 and does a very nice job. I'm upgrading to a 120, and since the skimmer is only a little over a month old, I hate to not use it. Would it be suitable for this size tank, with say a mag 7. The proposed set up will have a 5 inch dsb with over 100 lbs of LR. There will be 3 average sized fish. Is it workable? Would I need supplemental filtration, or should I plan for another larger (and more costly) skimmer. Thanks in advance. Is anyone usoing this skimmer on a larger tank and if so are you getting satisfactory results.
