But why do you have to use more chlorine if CYA is supposed to stabilize it? It would seem to me that since my CYA is 0, I should have to keep dumping chlorine in the pool, but the Best Guess chart says 1-3 ppm to maintain a clear pool? So if I up my CYA that means I will have to keep adding more chlorine to maintain? I doesn't make any sense to me
