This is my 2 cents, before u decide on what skimmer to get, ask yourself what will u be keeping in the tank? SPS, LPS, Fowlr? Alot of ppl misunderstand that if i use the best skimmer, my tank will be very good. Lesser maintainance needed.. but if u look ard in forum, there are alot of master who use normal stuff yet they have much nicer tank compared to those who think highend stuff mean nice tank.
