My pool gets lots and lots of sun. I've noticed that for the last 3 weeks or so, since I changed over to BBB that I average 5ppm CL loss per day. This turns out to be about 1 bottle (174oz) or 6% bleach per day.
I put in the bleach at night, measure in the AM, and there is no drop. However, when I measure in the evening it has dropped from 7pmm to 2ppm. My CYA is 80-100ppm depending on my testing vs pool store (80ppm me, 100ppm store).
Just wondering if this sounds OK? It drops even more if my kids use it. I'll go from 7ppm -> 0ppm if they use the pool.
thanks
