Why is my skimmer going nuts?

[andestang]

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

ok this skimmer is rly stressing me out.. it literally takes only 1 hairline of a turn for it to overfill like mad or bubbles to drop all the way down. when i do find the perfect spot it will work great for like 5-8 hrs then when i come back to look at it the bubbles drop all the way down again... what am i doing wrong? i raised the skimmer another 1' so its at 7" of water now and i have to tune it to nearly a fully closed air tuner for it to have bubbles near the top of the neck which i normally have for my other tank

mine does that i also have a vertex in180 its in 8" of water.
I get about an inch in the container over a week or so but the smallest turn and it overflows in 20 min.
I have a small bioload so i figured it was fairly normal since the 8" is the reccomended height IIRC but im sure I didnt guess when I made my stand for it.
so if i run it in say 6" of water you guys are saying I should have a easier time finding the sweet spot?
