So last night numbers were
CYA - 50
TA - 140
PH 8.2 plus
The highest the PH measure goes up is 8.2 but looked about like the right shade.
We added chlorine and muratic acid. We put in the muratic acid based pool math to bring ph down to 7.2 and bring TA down a little bit.
Today the numbers ph still 8.2 or higher. TA went up to 220!!!
Why did the TA jump and what do I do?
