	If you add enough HCl to get a sufficiently concentrated solution
for this to happen, _all_ the KH will be long gone, and everything in
the tank long since dead.  Hydrochloric acid is a strong acid, i.e., it
ionizes completely in dilute water solution.  It doesn't evaporate from
dilute solution.  You don't want any left anyway - the pH would crash.
