Ok, I have an eshopps sump, aqeon pro flex 110 overfolow box, Aquatop swp-2600 return pump, & coralife super skimmer 125 which isn't the best skimmer on the market, but I'm happy with the performance. The sump has 3 chambers, so what I did is hung the skinner on the first & added a maxi jet 1200...
