What is the max amount of baking soda that can be added in one day?

[Liza]

I have a 34000 gallon pool and need to raise alkalinity with 15lbs of baking soda. I have read that only 2.5lbs should be added a day. Another site said 10lbs/day is fine. What is the correct amount I can safely add in one day? Thanks for the help.

Why are you adding bicarbonate of soda is your TA so low
How are you testing
If your numbers are correct, I would be inclined to add half first of all, test again and then add the balance

TA is low from trusted pool store test.
What is the issue in adding too much baking soda at one time?
Is 2.5lbs/day or 10lbs/day or another amount correct?
Thanks

Let's have your numbers from your trusted pool store test

I suggest that you only add half so that you can adjust so that it doesn't go to high causing a swing in your pH (what's the problem with giving it two hits)
What was your trusted pool store suggestion
You can add what you want but make sure it is dissolved properly
