Here here!

Continuing on the soapbox, IMHO it is often the case that people unknowingly focus on pH as a surrogate for alkalinity, when they should just forget about pH and focus on alkalinity. Monitor pH as a secondary parameter. Proceed with caution if you are about to alter a working alkalinity maintenance regimen in attempt to solve a pH problem. Instead, nail your alkalinity regimen, then think about CO2 if your pH is out of whack as a result.

That's my approach at least, interested to hear from others if they have another take on the subject.
