5 days ago my T-100 test kit had my FC at about 11 and today it was at close to 2.
CYA is at 60 now which should be good for the rest of the year.
I brought it up to 11 because we were going to have a pool party and I thought the bathing load would need a little extra.
My CC is at 0, so no organic problems and the water is crystal clear.
If I understand the CYA chart the minimum FC should be 5 and target should be 7. My pool has been on the solar for about 10 days and the water temp is at 80 degrees and it has been very sunny and warm outside, 90 degrees today and a bit lower the last few days. Can I expect this quick of a drop for the rest of the summer in FC in a short time? Does the sun really deplete it that quickly ?!?
If it does, I can expect to use about 3 or more gallons of 8.25% of bleach every week. And maybe more when the air temp hits 100 or more for around 90 straight days soon. I'm shocked how fast the sun can deplete the sanitizer. Also, the warmer the water the faster the bleach is used up ?
I'm I right in my thinking ?
Thank you for all your help this year so far
