Looking for a new skimmer for a medium stocked 120 (40 sump). I currently have an older SWC 160 skimmer (Sicce psk 2500 pump) I bought used and have run for a couple years. Budget is 500ish (can go higher but of course would love to go less ) I feel performance has dropped off and I'm considering replacement. I was reading about recirc vs non and watching videos but opinions are conflicted. What skimmers would you purchase and why? Longevity is important - I fear change LFS likes Curve 7 any experience with Bubble Magus?
