I dosed yesterday, turned off my skimmer, and this morning I'd say 95% of the cyano is unaffected. Is there anything else that could be impacting it's performance/does it go bad?

 In my experience with chemiclean it takes more than a day for it to work.  It took 3 days for most of mine to start dying off and probably a week before it was all gone.
Also, I did not turn off my skimmer.  I took my skimmer cup off and let it overflow into my sump.  Made for a nasty display tank full of micro bubbles but I knew that was just temporary so I didn't care.  I wanted to make sure my tank remained oxygenated.
