So I threw a counter current protein skimmer last night. I've never had a skimmer before so I'm just wondering if anyone could help me out with possibly tuning this thing. It's made out of 3" pvc. It's 26" tall and the water level of the sump is around the 12" mark. the water is injected into the skimmer at about 20". Here are a few pictures from last night to this morning to now.
