Default water testing, and a chemistry lesson

CO2 + H2O --- H^+ HCO3^-

Adding CO2(acid) will never form the KH (-HCO3), a buffer in this
case.


Boboo. Not right. Some is formed, but _extremely little_ will be
formed in pure water. Enough to ignore it's contribution in any
practical case in a plant tank.
Absense of Trace metals will cause less bicarbonate to form.
