skimmer overflowing

[wearlesiii]

ok so when I woke up this morning I found my skimmer overflowing spilling into my sump. I have not added anything in the past week but I do have a CO2 scrubber on my skimmer intake so im not sure what is causing this .... not the first time.... it does it randomly it feels like.... any ideas?

You could inject some RO into the air intake line. That will dissolve any blockage in the Venturi.
