I need some advice on how to adjust for the daily consumption of CL by the sun. Oklahoma City. Hot and sunny.
the cya/cl chart gives me a minimum of 5 and a FC target of 7 for a CYA of 60.
I am losing anywhere between 5-10 ppm of CL each day due to sun, I pass OTCL.
If I assume I will have 8 ppm loss due to sun each day, should I add that on top of the 5 or the 7, and when should I add that CL, at night or in the morning.
I will probably raise my cya to 70. But even if I do, I may have sun loss that requires a daily dose above the target, and I am not sure how to calculate that.
