I've added what the pool calculator advised -- 50 oz of liquid chlorine (10%) and 61 oz of muriatic acid. It advised to add 166 oz of liquid stabilizer to reach 60 CYA. I bought two gallons, but chose to add only 128 oz (one gallon) and see what happens -- supposed to get me to 53 CYA. If I need to add more, I will. Just didn't want to add too much right away and regret it.
A couple more questions:
1. How long should I wait to measure FC, pH, CYA, TA, CH again?
2. How much liquid chlorine should I have on hand at home? I've got a bucket of tabs, but after reading up here I want to switch to liquid chlorine or bleach. Is $2.99 a gallon a good price for liquid chlorine (10%)? Local pool store has a sale going on at that price.
Again, thank you all for the input and advice.
