Just a reminder for all of us. My skimmer was looking good, but it was high flow and low bubbles in the chamber. It also seemed to be having trouble producing skimmate due to the low bubble count. After cleaning the whole thing and making no headway, I finally found that my venturis had calcium buildup just inside the openings right by the pump. I have been using it for about 5 years and never seen that before. Cleaned it out and tripled the performance. Hopefully this will help some other long term reefers that are having trouble with a good skimmer.
