Please describe what your definition of KH is.

KH is the carbonate hardness.

Yes, I know, the test kits measure alkalinity, not the actual carbonate
hardness. But in order to use the KH-pH-CO2 tables, KH is carbonate hardness.

So introducing bicarbonate (CO2 dissolved in water at this pH mostly
takes the form of bicarbonic acid) into water will not increase
"carbonate hardness"? I'm not sure I understand.
