I recently made the switch to BBB, and pool has been looking really good, water seems shiny and soft, and the amount of bleach to add has come down. Happy so far. However, I have noticed that the pH goes up to around 7.8 or so. I brought it down to 7.4, and within 4-5 days, it goes up to 7.8. Is it normal?
Test results are:
Is everything looking good or I need to so something about pH?
