My CYA is 75. Yes, I know it's high and this causes chlorine to burn off more slowly, correct?
I just want to make sure about this b/c between yesterday and today, my FC went down by only .5ppm (form 15.5 to 15). This just seems a little slow. The previous day, it had gone from 17.5 to 15.5 - but we also had rain during that 24 hour period.
I realize that the chlorine will burn off eventually, but I'm just impatient b/c we will be using the pool throughout the weekend.
