Have you tried raising it so you can actually control it with the valve.

Let in more air that should help.
Just my 2 cents but I think the skimmer is to big for the tank. U believe you asked a few months back and a few advised it was too large. I am running a super reef octopus that does 540 lph air on a 75 and it is too large to be consistent. You have over 3 times that amount of air. At 540lph this skimmer is rated 100 gallons at heavy load.
Also with this skimmer you can adjust the volute on the pump (white round "face") to set the amount of air vs water. Counter clockwise for more air clockwise for more water.
