I thought that the total hardness was the combination of the carbonate
hardness and permanant hardness.  I believe that increasing your carbonate
hardness will increase your total hardness by definition.  It is my
understanding though that carbonate hardness can be reduced by boiling or
other procedures to break down the carbonates.
