Sodium bicarbonate does not increase the "total hardness," which is a goofy
term for the total amount of Mg, Ca, Sr, and Ba ions in solution. It does
increase the "carbonate hardness," or alkalinity, and does increase the
buffering capacity of the water, but this buffering is not permanent. The
bicarbonate can be converted to CO2 by acids such as the peat acids.
