I've read to lower CYA that I need to drain the pool. What exactly does draining the pool do? I'm refilling with the same water supply that gave me the problem. After draining the pool some, then what??? Just fill er' up again or do something else? Here are my numbers
Water Temp/Time: 74/7:30pm
FC- 0 (I know, I went a couple of day and didn't add any bleach. Normally, I keep it around 3.0)
CC- 0 (of course)
CYA-unreadable, kit goes to 50 and no effect to the dot at all.
18' x 52 round AG Pool with 200lb sand filter.
Thanks for any help!!!!!!!!
