So ok, summer finally arrived in Ohio with 90+ degrees. All is well with my pool, and I have a fountain that comes out of the return and I really enjoy its sounds. However, I find I am fighting my PH rising to the 7.8 - 8.0 range when I leave it on for the day. Should I just keep adding acid to lower the PH and enjoy my fountain, or does the higher PH matter? (Inground vinyl pool - 10,000 gallons).
