granted, at shock levels, the pH readings are invalid.
And true, the pool calculator invaluable tool. I use it for all aspects of calculating chemicals to the pool.
And yes, a high TA prevents ' pH bounce '. Too high a TA you can get 'pH lock' - too low = 'pH bounce'.
Either the batch of TA + given to me had pH + mixed into it ( a little soda ash mixed in with baking soda.
I shouldnt get screaming high pH readings just by adding 24 oz of TA+ ( baking soda) into a 7,500 gal pool.
I cant really prove the pH is high like that because as TFP mentioned, the pool is at shock levels.
Also, near the bottom of the pool calculator, it does say for X amount of baking Soda added, X amount in TA will increase, and x
amount in pH will also increase. But the increase in pH is minute compared to the increase in TA.
I'll just have to wait until the FC's are at normal levels.
I could also try pure baking soda to see if the batch of TA+ is tainted from the factory.
But the increases are very minute to what the results i'm getting. But again,
