I loose about 2-3pm per day when it's 90-95 F. My cc is 0.5.
Does it mean that I'd lose the same 2-3ppm on the same day regardless of the CYA level?
According to Chlorine / CYA Chart the difference between minimum FC and target FC is 2ppm (for cya between 30-60). Also, in order to add 3ppm I need to add the same amount of chlorine, regardless of the cya level
I see my CYA level at 30-35, while leslies stores see it at 60. I wonder if by keeping it at 7ppm instead of 5ppm I'm wasting chlorine (assuming I have 30-35, not 60)
edit - I use liquid chlorine only, 12.5%
