That's the opposite of how what you'll see. As you aerate, your pH will rise with little or no apparent change in TA. The apparent change in TA will occur when you add your next dose of acid. Then, the pH will rise again.

You can simply maintain a pH of 6.8 to 7.0, while monitoring your TA. Once the TA reaches your target, hold the pH there, till the scale is gone.

But be careful. As your TA drops, it will take decreasing doses of acid to drop your pH.
