Keep in mind too much air will cause it to surge up and down, and cavitation can damage the impeller.

I find that the more I turn the white volute in the less height of the foam head I get. I started with 4 turns out, to 2, to 1.5 and now I’m at 1. When I screw the volute out the bubbles rise very high.
The stand pipe is completely open and I haven’t even got to the point of turning it as the water level and foam head is so high.
I checked the propellor and nothing is stuck in it. The Skimmer is only 2 months old as well. Could that cause the instability?
