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?

For some reason this photo didn’t show up on the previous post, so here it is.

Have you taken the entire Venturi out to inspect it for built up calcium?
I see it’s very new but doesn’t hurt to check
When you adjust it, you are looking for find bubbles to the bottom of the cup, and larger full ones above that.

Ya I have taken the Venturi out and it’s not gummed up at all. The Bubbles are fine at the base of the cup and the larger ones are popping past the half way point of the cone. At one point it was at halfway of the collection cup and the skimmate was perfect. Just can’t get the foam head back to halfway...it’s toward the top and the cup has been filling quick in 24 hours.

I drained the cup this evening. I will post a photo tomorrow when I wake up to show how much wet skim is being collected.

Well I have been turning in the Venturi every morning half a turn to hopefully get the foam head to be less and to not have half a cup of watery skim in 12 hours. I am now at half a turn from he Venturi being completely screwed in. At least the skim is a bit darker, the cup is less full and it’s not overflowing. Not where i want it but it will do for now.

Do you use filter socks? Are any of them new?

I have relatively new filter socks 🧦 on the system. Most have been washed a couple times though. I only change them when the first sock fills up and only the second one is draining.
