Well, Ijust got back from vacation. No testing for 7 days. Heres what happend. Had a neighbor add bleach every day and the pump was running all the time with solar cover in place.

Sat. Rained all day. Removed 2 inches of water, tested then left.

Sat FC 15ppm
Sun added 3qts 6%
Mon 6qts 6%
Tues she forgot
Weds 3qts 6%
Thurs 6qts 6%
Fri 3qts 6%

I got home sat at 1pm. Tested
FC 7ppm
CC 1ppm.
I really expected FC to be much higher with cover on and no swimming.There was about 1inch of rain added over week. Then I added bleach tested at night. FC 12ppm. This mourning it was 9ppm. Something isnt right. Im gonna test my cya again. I really dont know whats going on. i thought we had it under control.

Ok.

Well, I don't know. I've recently seen some high demand here, but with different conditions. I could speculate, but I really don't have any solid ideas. Your chlorine use is higher than I'd expect, but I don't know why.
