I've been using tabs to supplement bleach for 2 weeks. I drop 3 tabs a week, so 6 tabs so far. For my pool size, 6 tabs ~ 12 ppm of chlorine and 7ppm of CYA. And I have been testing CYA twice a week, but noticed no change. For full disclosure, I may have added about 15 minutes worth of water via garden hose to compensate for regular water loss.
I was under the impression CYA doesn't go down by itself unless you dilute it with water. But it seems to me there is some sort of burn off of CYA, does this have to do with high temperature? My pool temp has been hovering around 90F.
