I am attempting to make a batch of CS but having little (NO) success.
I can't figure out what I'm doing wrong, maybe the power supply?
Silver provided by 2 .999 pure US dollar coins (recent vintage - not the
old coin silver kind)
2 quarts distilled water
aquarium pump to keep things moving.
And, the power supply is a transformer with the plug removed and leads
attached to the silver rounds. It provides 6V of direct current at 2000 ma.
## 2000 mA is the max rated current draw that the supply will deliver 6
volts at.
Unloaded, if it's an unregulated supply, it will probably put out around
9 volts.
9 volts in good distilled water will emit ions very slowly and the
current draw at that voltage will be well under 1 mA
1 PPM [2 uS?] in 16 hours isn't surprising in a volume of 2 quarts.
To speed it up, locate the electrodes closer together.
Conductivity controls current draw at a given voltage and is higher with
less distance.
Using 1 oz coins with their surface area and configuration, I'd not
exceed around 3 or 4 milliamps...maybe less as there will be loads of ionic
edge discharge with the backside doing almost nothing and the center very
little.

I have run this setup for about 16 hours, but the water still reads to
show 1 ppm.
I'm assuming I need to use a different power supply. Suggestions?
Thanks. Steve Grover
