Help! My Vertex Skimmer is actin crazy!

[Timbits]

Hi guys i really need your help, i have a Vertex IN-250 and lately its been acting crazy! Basically, its not skimming and fills the cup too fast. I tried adjusting the air intake and lowering the water level and it seems to help a bit but now i have it on almost open and the water level is like half of the suggested operating level.

I don't know what to do and it's driving me crazy!

Please help!

Have you dosed anything lately? I find sometimes with mine it goes crazy after dosing. It takes sometime to work itself out. At these times, I take the little plug off the skimmer cup and run a hose to a bucket until it works itself out. It does this after water changes sometimes too.

When the intake is tight how many turns are you opening it?

you mean on close? initially it was just a lil to the left, just one tiny turn but now i have it almost all the way open

i have a vertex IN-80 on another tank and that one never has any problems. even after water changes, it never acts crazy. when i do a water change on this tank, the skimmer just bubbles just under the neck for a lil while and then starts skimming again, never overflows

would high nitrates be a cause? or too much top off water added to sump at once??

i know it goes crazy after dosing or a water change but lately its been doing this every day it's pretty ridiculous i unplug it, turn it back on the next day and it still does it
