Pool Questions

This morning the chlorine reading was 17.5 ppm... is that a drastic drop in 24 hrs? From 31.5 to 17.5? The pool is clear, clean & blue.

If you added chlorine after the sun was low enough to end most direct sun, and then retested before there was much direct sun . . . then yes, that's a drastic drop.

Otherwise, no.

But if your water is clear, I'd go ahead and let it drop to the 5 - 10 range and hold it there for a week. After that you can operated normally. But do follow the Best Guess Guide (link below) to establish what "normal" is for your pool. At 60 ppm CYA, 5 - 10 ppm chlorine IS normal.
