Thanks again. Just went to bed with FC 29 Woke up to 24ppm. Wow im going through alot of bleach. before i started this i used about 60 gallons just trying to keep my pool clear not relizing that i wasnt solving any problems. last year i did the same thing. Many moirnings of waking up to a cloudy pool. I posted another problem with no replies. I know i shouldnt worry about this yet but my concrete deck is pitting like crazy. Many kids dumping water on deck. No calcium at all. Should i eventually add some for my concretes sake and not my vinyl liners sake.thanks
