So, I got everything for making CDS completely close looped using a
tiny chemical resistant rotary vane pump.

The jars are old IV bottles made back when the medical industry actually used glassware. The little jar on the left is empty except for ten drops of MMS and ten drops of activator. The large jar on the right I start out with pure distilled water.
With this setup there is no waste and you can just run it until you have the concentration you want based on the color. Works like a charm. I set the power supply to about 2.5 volts @ 60mA and let it bubble for about 15 minutes. Then I take the distilled water that now has dissolved chlorine dioxide in it and add a little to some fresh water, about 20% ClO
2 to 80% clean water.
The really odd thing about this process is the water gives you an odd feeling of being a thirst quencher. It's not something I would have expected. It just tastes wet, if you know what I mean by that. I don't know about most people, but lately it seem like I am always dehydrated, no mater what I drink. With this mix, that sensation has gone away.
