After some more rains, PH hit 8. I added acid yesterday, about an hour before some of my daughter's friends were coming over. I had planned to drop ph to 7, but only had enough acid to get to 7.2.

They swam for a good 2 hours, hit the diving board pretty good, lot's of aeration going on. I tested the pool this noon-

PH- 7.2
ALK- 80

This is the lowest I've ever gotten my alk. Richard, with these levels, according to your graph I should now be relatively stable, right?
