Help! Bicarb start-up bucket method pool filling

[tjk65]

Doing 5 gal bucket method. Checking every two hours.

Fill water
TA 150
CH 200
PH 7.2

1st Check
TA 180
CH 225
PH 7.5

2nd Check
TA 140
CH 225
PH 8.0

Do I base my calcs on 2000 gallons of water. I believe 1K went in at 2 hr. So, I am thinking 1K every 2 hrs. Then I would assume I need .98 lbs of baking soda. How do I determine acid needed?

Thanks

Maybe @onBalance can provide guidance.

I think adding 1 or 2 ounces of acid per lb. of baking soda should be plenty. Monitor the pH and add more acid if the pH goes above 8.0. Don't add any acid if the pH is below 7.5.
