I ordered the CST3 with timer (high voltage 33v output)
from goodvitality.com It only uses a 9v battery so not sure how you get 33v output from that.

## They probably use voltage doubler chips, but voltage is virtually irrelevant and timers can't work to predict much with so many water variables involved.
IOW  Whoever makes these, doesn't have a clue.
You'd be better off with just the 9 volt battery.



Im not sure about using an air pump because that is putting a plastic tube in the
water while creating cs...

## Plastic isn't a big problem, but aerating the CS with air pollutants can be. To some extent, bubbling Carbon Dioxide into the water will make some Carbonic Acid which will form Silver Carbonate, a Photo Reactive compound...and excessive Oxygen will make some Silver Oxides that tends to make a batch yellow.

If you have an air freshener in the house, various cleaners or Sulphur Dioxide gas from an upwind coal fired power plant????
The results are anybodies guess.

A few large bubbles will move the water fairly harmlessly, many small bubbles may contaminate it.

Any help and suggestions are kindly welcome.
