Welcome to the forums
These tests are what most of us use and recommend. A common myth is that pH is crucial to fish health. This is only true to an extent, as long as the pH is fairly neutral most fish can adapt to it.
If you start using chemicals to change the pH it can get messy (expensive to add chemicals every water change, and often the change in pH is rapid and stresses the fish). A stable aquarium where the pH doesn't change all the time (even if it is a tad higher than recommended) is better than constantly changing the pH.
Just monitor pH to make sure there's no big swings and the fish should be ok
what's more important is the ammonia, nitrite and nitrate readings. Did you get the API master kit that has those tests too?
