Hello All, I just opened my pool my water is 99% clear but for some reason I have no FC I am guessing it is because of my CYA numbers my tc is 2.5 fc is 0 ph is 7.5 ta is 100 cya is 20. I added 2 bags of shock so that I could get the cya in the water for the initial opening I know using the bag shock will drive up your cya that is what happened last year before I found tfp I checked my numbers and then added 1 bottle of bleach and then another and then a half of a bottle and after that I checked my numbers and those are the results that I just gave you. So should I continue to add bleach and whats is a good cya a number for NY I am in beacon, ny on the hudson river? Thanks for your help
