Thank you, Watermom. So I added another gallon of Walmart 8% bleach early this morning and my pool service added some acid last week.

Here are my numbers:
FC 11.5
CC .5
Ph 8+
TA 160
CH 52

I looked at the best guess chart but don't understand. For my high cya number, should I be aiming for FC of 8 to 15? What does the shock column mean? I need to have my pool swimable by the weekend. Would you advise me to drain some of the water?

Thank you so much.
