KH comes from both carbonate AND bicarbonate; they are in equilibrium
and their proportion depends on pH.  It's strange that 'total
alkalinity' is less than bicarbonate.  Perhaps some other acid is
reducing the total.  Note that this situation would throw off a CO2
reading determined from a KH/pH chart, since most "KH" test kits 
measure total alkalinity, not just carbonate hardness.

Hmmm, "General Hardness" is usually Ca AND Mg but the values here seem to
indicate just Ca.
