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).
That's really up to you--some say that the higher pH is easier on the eyes, but lower pH makes the chlorine more effective. Also, if your CH is high, the high pH with high TA will make the water cloudy and milky-looking as the calcium "falls out". So...if your water is clear and you are very consistent about your chlorination, the higher pH probably will be okay...but if you start having any kind of problems, you'll need to lower it.
