Colloidal silver at any concentration is better than none.  In most cases,
you will not have access to a laboratory capable of telling you accurately
what the concentration of your latest batch of colloidal silver really is. 
However, there are a couple of simple tests you can perform.  You can shine
a light through the water and you will see where the beam of light passes
through the water.  This is called the "Tindall effect" and if you can see
this you know that you have been successful at creating a colloidal
suspension in your water.  As you look at your batch you should notice the
color of the water.  Any color from red to yellow to green is an indication
your particle size is correct and that you have definitely acheived an
adequate concentration to be effective.  The darker the color, the stronger
or higher is the concentration of colloidal silver in the water.  If the
concentration rises to a high enough level, the color will change from a
deep color (lets say it is golden color for example) to a brown or black
color.  If you can dilute it and end up with a pure red, gold or green
color, then you know that you have a very concentrated, and good batch.  If
you are not going to use it up quickly, you will probably need to dilute
your batch in order to be sure it will not settle out in time.

The Bob Beck equipment uses about 27 volts to form colloidal silver.  All
the equipment I have been involved with used much higher voltages (over 100
volts in most cases with one experimental device using 15000 volts).  I am
not sure if the lower voltage devices will get the concentration to the
level where the suspension will look brown or black without being run for a
very long time.  I do know that they can make colloidal silver that is
biologically effective.  My main criticism of these units, at the present
time, is that they use up batteries quickly and those 9 volt batteries are
not cheap.

I have never worried about getting too much colloidal silver.  One of my
friends who rediscovered colloidal silver in the mid 1980's, in order to
prove to the group that was collaborating on the project that the product
he had come up with was not toxic, drank a gallon of dark, highly
concentrated product every day for a week.  About the only thing that
happened is that he has not had a cold since 1985.

As I said earlier, all my experience has been with the higher voltage
devices.  I have not really studied the Bob Beck device or the protocol for
using it in detail.  I am about to obtain the circuit diagrams and related
information for this device and perhaps will be able to comment on it in
the near future.

The dumbest question is the one not asked.  I am happy to share what I
know.  That is the whole purpose of this group as I see it.

Good luck with your colloidal silver.
