Last time I tested water was 09/02 and CH was 250 today the water temp hit 60 so I wanted to get FC up to at least 5 to combat algae. Tested CH at to my surprise it was 0..
FC 0 Added 3 gal to get it to 5
PH 8.2 will add 2 qts acid to get that to 7.5
TA 170 I've always had trouble with TA in this pool
Could the Could the r-0010 or the r-11l gone bad over winter? I keep the kit in the house. No extreme temps.
Thanks for any help.
