Well my skimmers here and after 5hrs of tweeking I *think* I may have gotten it right I'm going to let it run for a few days without touching it~maybe....How long should it be before I see some skim mate?
Depends on how dirty your tank is. Could skim right away, could take a while. Some skimmers, particularly brand new ones, will need a break in period before they start skimming. They need to build up a slime coat before they will skim. Some- not all.
