I just finished shocking my pool with bleach, 2 days ago I put in 4 lbs of CYA and enough acid to bring the PH down from 8 to 7.2, my TA at the time was 120. When I just checked it my PH is at 7.2 but my TA went up to 140, my FC is still a bit high at 10. We had some rain, less then a 1/2 inch. What could have brought the TA up? I am testing all this with my Taylor Test Kit.
