Is this a _measured_ KH? If so, are you sure it _is_ KH?
Measurements of KH are usually just "alkalinity" titrations,
and will measure the total of all anions of weak acids. If they
claim that a given mix will give a pH of 7.0, regardless of the CO2
concentration in the water, then the main buffering system there
isn't bicarbonate/CO2.

Don't use them, then.

It is quite sufficient to use CaCO3 and NaHCO3 to get the GH and
KH you want. The chances of understanding what is going on are pretty
slim when you don't know what you are putting in.
