Look at steveg's pic in post 787.
I'm referring to the air/water line. skimmer will have 3 zones. Lower turbulent zone separated by a fairly fine line of more uniform bubbles rising above that. The line in red on his post is the air water line. That's what I'm referring to. That line should be around 1/2 to 1 inch from the white collar the cup screws onto. Hope that helps
Thanks for clearing that up. I have had my line at the collar and not below it as you have suggested. I have fixed it so we will see what happens.
