Looks like your on the road to recovery.

Watch the PH bounce and do your best to keep it in check. 7.2 - 7.3. Your Alk level appears to be pretty good.

Something I learned from some other posts to help manage the PH is to lower your PH to the 7.0 with the MA and then Airate the water with a waterfountain or something to bring it back up.

**I used to have my water feature on all the time and could never figure out why my PH level kept rising....

Happy swimming.
