The pool has been on the Clorox bleach only diet for about 5 weeks. It looked great. My CH was at 225 and I want to get it up to 300/350 range. Since I have several left over pounds of Calcium Hypochlorite 57.8% I thought I would just use that for a few days instead of Clorox to treat the pool and raise the CH. I only added 2 lbs and while I can still see the bottom of my pool it went cloudy for about 24-36 hours. Is that to be expected since it really hasn't seen anything but bleach for 5 weeks? Also, is there CYA in Calcium Hypo? Thanks.
