Skimmer Issue?

[SmyrnaReefer]

i have a reef octopus skimmer, the issue is that the level is fluctuating in the neck. i can set it just below the cup and the next morning its 2 inches lower, sometimes a little higher. skimmer has been running for about 5 weeks now. its still making bubbles and foaming, just the level is causing issues. there is nothing blocking the pump and the level in the sump is staying constant. any ideas would be appreciatted.

i would try to place it a bit higher - not on the ground of the external sump - just 5-8cm higher if possible

Are you still getting skimmate?

Have you checked the venturi and air inlet to ensure that there isn't any debris restricting them?
