This is not how it works.
One single electron is removed from each silver atom, creating positively charged silver ions, not chunks of silver. It is very important to use only distilled water when making a batch of colloidal silver. The reason is simple. You must start with pure water, void of any chemicals or minerals.
The resistance of distilled water is very high and this is very important because it needs to be in order to make proper colloidal ionic silver. If you start with any other type of water, it will greatly affect the quality of the batch.
The bubbler I believe has two funtions. One is to introduce carbon dioxide. The other is to keep the solution mixing.
The sole purpose of the bubbler is to constantly stir the silver ions, thus keeping the solution "balanced". There is no carbon dioxide produced.
I think this helps the particles of silver from amalgamating,, espcially inbetween the two electrodes.
This is also not true.
The silver being produced is ionic silver, however, silver particles are also being produced. These silver particles are bigger than the silver ions.
Once the solution is completed and is stored in a glass or approved plastic container, a process called agglomeration
takes place. This process consists of the silver particals "absorbing" some of the silver ions. This will take place over a few days to a couple of weeks, and it is this process that gives the silver solution its golden color. The solution also gets darker as up to 50% of the silver ions become absorbed by the silver particles.
This does not mean the solution becomes weaker. It only means there is now more silver particles and less ionic silver.
Just a word of advice when making your own colloidal silver generator. I made my own generator years ago, but instead of using silver rods I used two pure silver Canadian Maple coins. I used reverse osmosis water, which was a mistake. I also didn't have a TDS meter, so I couldn't measure the total dissolved solids in the water I was using, thus, really had no idea what quality of silver I was making.
The bottom line is start with distilled water. That way you know you are going to produce a decent silver sollution. Also make sure you clean the silver rods after each batch. This is very important because this will help to keep the solution free of silver hydroxide, which is something you don't want in your solution.
Buy a copper pot scraper to clean the silver rods. Copper cleans silver! These copper pot scrapers cost only a buck or two and you will be surprised how good it works to keep the rods clean. Other than that, don't contaminate your silver rods by touching them with your fingers or any chemical cleaners... just copper and kleenex, and use only distilled water to clean the glass container that you use to make the solution in. Don't use a metal container or plastic.
And finally, keep your finished product out of direct sunlight.
