I have a question regarding the CYA/FC levels in a salt water pool.
I would like to keep the CYA levels lower than what is recommended by the manufacturer. My goal is to have a CYA level of 20ppm or less. Personally I don't see a problem with that but I'm curious why the recommended levels are a lot higher than that. I am using a Hayward Sense and Dispense system to maintain 650mV ORP and the pump is running 24/7 (variable speed pump).
