If the MA was full-strength (31.45% Hydrochloric Acid), then your pH would have dropped to 6.84 and your TA down to 88.2. Adding two boxes of 20 Mule Team Borax (76 ounces for each box) would raise the pH to 7.15 and the TA to 101.2. The pH might be higher from carbon dioxide outgassing. If it's not, then you could add a third box of Borax. Don't worry -- this isn't a disaster and the exposure time to the lower pH was short. If he poured quickly in one place not over a return flow, then that could weaken the vinyl in the area where he poured, but hopefully that's not what he did.

I'll add bleach to bring up to 10. Then should I add baking soda to raise TA or Borax to raise PH or our these numbers OK and leave to rise on their own?
Thanks for the support

You could just leave it alone. Or aerate. But you don't need to add anything else for pH. Haven't you traumatized that pool enough recently? :mrgreen:
