Waterbear, thanks for the response.

I use a Taylor kit for testing my pH, TA, CYA etc and Taylor FAS-DPD kit for testing CL, so bleaching should not be an issue.

I'm below your 10-15 CL level so think my pH test should be reliable.

I added two more cups of the Sodium Bisulfate to my 24K gal pool about 4 hours ago and the pH has moved to about 7.6. Now I have to watch it because if history repeats itself it will inch back up.

If pH keeps inching up, I will follow your advice for lowering the TA to 70. Here I was real proud of myself for nailing the TA right in the middle of the recommended range at 100.
