My 1 month old pool has been crystal clear ever since the plaster dust went away. I have absolutely LOVED this site and treated it as pool gospel when it comes to testing (TF100) and using PoolMath to adjust. Everything has been great but it seems like I'm going through considerably more chlorine than I would expect. Cloudy days will consume approx. 3 ppm FC, but bright sunny days are eating 6-6.5 ppm FC!
My latest test results:
pH 7.8 (pool pretty much lives here despite 16 oz MA every night)
FC 3.5 (end of the day, prior to re-dosing. Bump up to 9.5 or 10 each night to account for daytime loss)
CC 0
CYA 30-35 (I think -- standard newbie lack of confidence on this test)
TA 70
CH 75 (stays persistently low -- might have to supplement this against all recommendations so far to keep CSI above -0.6 at lower pH - if I ever get there)
At least it's been consistent for the last 2 weeks. I have done a couple of overnight chlorine loss tests and passed. Of note, my pump doesn't run at night. I'm not sure if this would cause a false pass in the overnight test or not.
I've considered increasing CYA to 50 or so, but it still just seems like I'm loosing an excessive amount of chlorine, even at my current CYA level.
If it matters, I do have high evaporative loss on hot days as the wind blows pretty good at my house most of the time. I'm replacing about 1/2" per day.
Other than increasing CYA to around 50, should I be concerned about anything else?
