If you are dosing and the doses get screwed up for some strange reason (Pump failure, etc.. , your pH will change for sure. ALK + MAG + CAL all have an effect on the pH

(If you are actively monitoring your other levels, then yes pH is something I don't think you need to monitor. Just wanted to toss that extra information out there.)

While that could happen, causing a minimal change, the first thing to do after a dosing pump failure (where it fails on) would be a large water change, restoring any shift in pH. If it fails off, and Ca drops to 350, still not a parameter that I would worry about. I did this number chasing game for months when I started, and I ended up fixing my pH problem by throwing away the meter My tank's doing ok without it, AND I use CO2 in a reactor.

So sure, if you've got the money to spend and the time to chase numbers, go ahead, but I can think of a lot of other things to spend the money on (like repairing that broken dosing pump )
