To figure this out, test the tap water and the tank for:
If the tap water has the same mineral levels (GH, KH, TDS) and just the pH is different then it is probably just fine to do water changes. Fish react to the changing mineral levels worse than changing pH.
If the tap and tank do not have the same mineral levels then lets figure out what is going on.
