Well, I've been maintaining my new pool since late May, of course with the help of the pool math app and the TF100 test kit. I live in Florida and have a screen enclosure due to mosquitoes and a large oak tree nearby; not saying it's a must here but.....it is!
As expected, with rain and evaporation, my CYA has been dropping over time. With my SWG operating at 70%, my FC was slowly increasing as my CYA went down. Using the TF100 and monitoring, my FC finally got up to 7.5ppm with my CYA at 38. This was surprising and puzzling since I figured the lower CYA would show a reduction in my FC, not an increase. Anyway, I turned my SWG down a few weeks ago to 50% and my FC is now 3.5ppm with CYA at 25. CC has remained consistent at 0.5ppm since the pool has been running. pH is ranging from 7.0 - 8.0 with 3-4 day acid additions by me.
I was wondering if the screen enclosure could be blocking that much UV and therefore a lower CYA amount is ok? I guess it could be a good problem to have but just wanted to be sure the CYA didn't affect anything else other than chlorine breakdown.
I look forward to getting some input on this.......
