Once you get your borate level to 50 ppm, there have been some that report stabilization of pH (as well as lower chlorine consumption, in some cases) but keep in mind that the rest of us use Borax to raise pH, so when you're adding it to maintain your borates, you're going to have to compensate with a little acid to keep your pH from rising (which should also help keep your TA lower, as well).
