If you are using a meter to determine the PPM, you may not be measuring what you think.
Any time there is an open air arc or plasma, nitric acid is being made.
Nitric acid is an extremely good electroyte and will make a meter read very high with virtually no silver present.
If it's made in the presence of silver ions, silver nitrate is being made.
On a rig such as this, it's important to use an inert gas blanket to keep air away from the unsubmerged electrode.
Some companies that may be making this error are listed here.

'Sorta' contrary to what the silver-colloids web site says, you can use a meter to get a sorta good "idea" of silver content, but only if you know that that's what you're measuring and not something else and it won't even register anything at all on a true colloid or any true colloidal content.
Meters are by no means a direct measurement and they don't discriminate.
300PPM and clear sends up a warning flag. Maybe possible but not likely...probably could use further scrutiny to be sure.
Silver nitrate is not especially user friendly.

How do they work.<<<<
<> They use High Voltage (15,000 volts {15Kv}) of AC. One silver electrode is placed into the water. My unit has High Voltage cable with an alligator clip on the end. I just clip a "Trader's Round" on and bend it so that the coin is mostly under water. Do NOT let the steel alligator clip get into the water. The water will tend to 'climb' up while the unit is running.
The other lead had a silver wire clipped on and it is suspended about 1/4 inch above the surface. This limits the current to produce smaller particles.
I use a 1/2 gallon Pyrex bowl to hold the DW for 'cooking'.
How long does it take to make 300 ppm?
At 15Kv the unit will produce 15ppm per pint per hour. The 300 ppm cooked for about 20 hours and is probably much stronger as the temperature of the DW continuously goes up and so does the current.
Where can I buy one at?
The man that made these no longer does so. However, the power supply is a commercial Neon Lamp power supply which should be available worldwide.
In the last week (?) there was a post for making a CS Gen out of a microwave oven. THis is intriguing! I am planning on trying it. Not only does it salvage a microwave in which the bad part is usually the magnetron (removed to use for CS) it also provides a measure of safety in that it only works with the oven door closed. Neat.
The source of the Neon supply should have the high voltage wiring you will need.
