Hello all. I began my time here this week as a new member by reading everything I felt was relevant in Pool School, including basic pool chemistry and chemicals.
According to the chart, since my CYA is at 50, my target FC level should be between 6-8. I had a tad bit of white mold (I think - looked like shredded tissue paper) in my pool when I opened it this last week (I just bought this house last year). I read to triple or quadruple shock to get rid of it, so I did. I did an overnight FC loss test last night, and didn't lose any FC at all (went to bed at 15.5, woke up at the same). Since it was still that high, I read about safe levels of FC for swimming. I read that one shouldn't swim at all when FC is greater than 10.
This brings me to my question. Since the chart shows my target FC range is 6-8ppm, but one shouldn't swim if it's over 10ppm, I'm assuming that leaves me a small window within which to keep my FC levels? Also, with that suggested range of 6-8ppm, would there still be some irritation to the eyes and skin? Aside from the chart, I've read elsewhere the suggested ranges for FC is anywhere from 1-4.
Any thoughts that may help, please reply. Thanks!
