I'm going to have to give you some different instructions.

1. Test your pool's pH each evening. If it's above 7.2, add 1/2 gallon of MA. Make sure the pump runs for at least 4 hours after. Do NOT test TA or CH during these 3 days!!! Continue to aerate, using whatever approach you've chosen.

2. After 3 evenings of testing pH and adding MA **as needed**, the following (fourth!) day test the TA.
==> If the TA is <150, do not add acid for 3 days. Do *NOT* test the TA again for 3 days. Discontinue acid additions during this period.
==> If the TA is > 150, recycle to #1 above.

3. After waiting 3 days (after a TA reading < 150 ppm), retest both pH and TA, and report results here. Do NOT test either pH or TA during the 3 days you wait.

OK?

Under NO conditions should you ("BromineUser") test TA more than 2x per week.
