High PH in new water?

[Randy Holmes-Farley]

Usally let sit 12-14 hours after mixing it test it and do my WC

This batch sat for 13 hours , tested it and the results are in 1st post.

Did the first batch have white solids precipitated?

No or at least not that I saw

I have a hard time explaining how the alk dropped and the pH rose in batch 1 to batch 2 without precipitation.
