Not Skimming

I've had a FO set up for 6 months and now I've decided to go to a FOWLR. I added already cured live rock 2 weeks ago. It is a 150 with a maroon stripe clown and 2 eels a few hermits and snails. My Aqua C EV-180 has been skimming fine until yesterday. I noticed 1 of the air intakes was clogged, so I cleaned it. Now I'm not skimming at all. Is it due to a cycle?
Thanks In advance for any assistance in this matter.
