All my numbers are good except I cannot get my CYA up to 70-80.A month ago I tested it at 50 and added the required amount of stabilizer.A week later no change.I did it again and a week later no change.Even went to pool store and they get same numbers. My phospahates are 500, they tried to get me to buy stuff but said no. They got a little snotty after that. I have read about all of you with high phosphates and it not being a problem, so I stayed with that advice.Any idea what would keep my CYA down? I will say my pool is small and us large dads cannon ball a lot of water out to get our kids screaming "Bering Sea! Bearing Sea!" lol
