If the total alkalinity is in the right range, pH won’t be so volatile.  If your pH is bouncing, chances are the TA is too low.  TA is the real driving force to controlling the pH.

If a service tech or do it “yourselfer” doesn’t understand this relationship, poor water balance can result.

TA is the governor of pH.    Don’t try to change the pH unless the TA is in the right range. The first correction is always TA…then you address any pH issue. And you may never have to change it if the TA is OK.

Here’s a look at exactly what pH and TA are, how they relate and interact and what service techs can do to keep it all under control.
