1) Lower PH (Pool calculator – 22k gallons, target 7.2) = add 65oz muriatic acid
a. Do I target 7.2 or 7.5?
b. Based on JasonLion’s post I read, I will pour it slowly in front of a return jet with the pump running.
c. Do I pour 65oz one time or should I divide them and allow time between each part?
d. How long do I have to wait until I can test the PH?
e. The only test for PH is the Basic OTO test, correct?
2) Only after my PH hits the target level, I will start slamming…
a. I can start slamming at CYA – 20, correct? If yes, I’ll increase FC to 10 (Pool calculator – 22k gallons, target 10, 8.25% bleach, 128oz jug) = 332oz. Since, I purchased 64oz jug, I double the number to 664oz. 664oz/64oz jug = 10.375. If I understand and did this correctly, I will need to pour 10-11 jugs of Great Value 64oz (8.25%) of bleach.
b. I will retest every hour and continue to add bleach to reach FC level of 10.
