I may have this all screwed up. I've been shocking my pool for the last 24 hours. No problem holding chlorine. I added the recommended dosage of polyquat 60 for winterizing my pool last night after dark. This morning I woke up and I failed the OCLT. Do I need to start the shocking process all over or does this have something to do with my addition of polyquat 60?
