It is recommended that your FC is 7.5% of your CYA levels. This ratio determines the active chlorine levels needed to prevent algal growth, not just FC alone. For example, if your pool started with 30 ppm of CYA, then 7.5% of 30 ppm is 2.25pm of FC. As your CYA increases, higher levels of FC are needed in order to prevent algal growth.
