If you are asking what "normal PH is", then anywhere between 8.2 and 8.4 IMO is good.
AGAIN this also depends on your other parameters. Just making your PH 8.3 or 8.4 isn't going to make everything perfect. This can drop your alk and mess up lots of things.
IMO mix your water for a minimum of 24 hours and then test the calcium, magnesium, alk, and PH then post your parameters on here.
