I'd be patient. Keep the skimmer opened up fully and just let it do its thing. Toss some activated carbon into the system too, can't hurt anything.
I had issues with my skimmer doing this for awhile and after a month of having poor skimming I took it out and ran it in vinegar solution and now it is going great. Just let things go par for the course. The stress coat stuff can't the that awful on your system.
