I question whether anyone really needs a pH monitor on a reef tank. If you are measuring your Alk and your Alk is high enough, your pH should automatically be OK. I have come to the conclusion that my fish and corals don't care what the pH is and I focus on Alk, not pH.

I mostly agree. Measuring the tank pH is largely not necessary. It is cool, though!
