Okay, my CYA is showing 10. Last year it was 40. No water level changes since last season. My pool temperature is 59 degrees. Does that matter on CYA readings?
PH - 8.0 +
I am trying to keep my pool at 12 ppm (Shock level), but it is dropping so fast. Within 1.5 hours it dropped from 12 to 2.4.
Pool is cloudy Grayish Green and hasn't changed in 3 days with 12" depth visibility. Suggestions?
