My Ph is 7.2, CYA is 120+, FC is very low. My neighbor told me that I could add as much stablizer as I wanted, you couldn't add too much. Unfortunately I believe I over stabilized and the excess CYA is grabbing all the chlorine I keep adding. Is my only alternative to pump down the pool water and add new water to lower the CYA to 70ppm and then add appropriate amount of chlorine?
