Why is my skimmer going nuts?

You see the water level in the neck going up and down and you can also hear it from the pump.

Mine was doing that. Goes up down n super hard to fine tune. Even adjusting the tuner by a hair line will cause huge fluctuations in skimmer lvl. Found out that my pump was not in straight it was a lil crooked. It now doesn't fluctuate by tuning it is so hard. Is this normal for vertex IN series? Litterly 1 hair turns makes it either g half way down in bubbles or super overflowing
