First year not using easy pool. Trying to understand how to calculate cya levels to know how much chlorine to add. Bought the taylor kit so it says cya is at 30 ppm and fc is at barely 1. I have above ground pool that holds 17k gallons of water. According to the handy chart if my cya is 30 ppm i should have between a 3-6 on the chlorine? How do i determine how much chlorine to add? Sorry in advance for the dumb questions. Thx
