Water source for CDH, or NaCLO2

That would probably work. I sometimes use our well water to make CDS. 

Usually I filter the well water using a Berkey and two Zero filters, one after the other. 

Or, make distilled water. 

Can I use water from my Zero water pitcher to dilute the MMS1?  I have a Berkey system, but it doesn't remove flouride like the Zero water filter pitcher does.
