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.
