An interesting post Allan and a pretty thorough run down on what happened -
thank you for the information.

To the best of my understanding deionised water has been passed through an
ion exchange filter so any reactive particles are removed.  Distilled water
has been distilled (evaporated and condensed) and this does not mean it is
totally unreactive.  Any volitile compounds in the water may have been
distilled also and still be in solution.  It will be sterile though.

The water I source here in New Zealand (maybe not availalble in the States)
has been through both processes and is sold as a food grade product for
manufacturing tinctures etc.  Dirt cheap from a bulk retail store unlike
distilled water which is pretty pricey.
