Thanks Nevelle, its just the first lot of DW I 'brewed' came out at 000 on the 
TDS.  This was just water boiled in the kettle and then put in the distiller.  
The second lot went through a Brita filter first before boiling and then steam 
distilling.  after the first time, it read 002 on the TDS so I distilled it 
again.  Then it came out at 003!  I just can't understand it at all.  
The tyndall was in water from the first batch *before* I put the electrodes in, 
so I don't understand that at all either.  dee
