Klaes power protein skimmer

Try cleaning out the venturi air intake. Shoot some hot water through the air intake at very high pressure. That should take care of your problem. Also place a contol valve on the out port of your skimmer. This way you can control the water level in your skimmer and produce a constistant foam. Also what size pump are you guys running on the skimmer? I use a Mag7.
