If your fish are fine I'd advise against trying to alter ph. Matching your tap and no issues? No problem.
Just got an API master test kit and tested my tank water. My pH is at like 8.4 or something, and my tap water is around there as well. How can I fix it?
What about fish that require a certain ph? Would it be advisable to alter it then? Like blue Rams for example?

If they are bought locally it's highly likely the LFS uses the same tap water as you therefore reletively same pH. Wild fish are the ones that you would need to worry about pH. Captive bred can adjust pretty easily with enough acclimation.
