I checked for CYA while slamming was in progress . It was 55-60 last year.
Filled to the top and I can still see the black dot clearly . So kind of showing that it is way below 20
Pool was filled to the brim when I opened this year. Had drained 0.5 feet below skimmer before closing lasy year oct.
Could it possible to get such a low reading in year and with snow and rainwater?
Taylor test kit is from last year and chemicals expires in 2019.
Thanks for any suggestion/comments .
