Colloidal Silver
Follow the instructions that come with the generator and you will make very high quality
Colloidal Silver at any time of the day or night. However, there is a best time to make colloidal silver every day. Contrary to popular belief, colloidal silver is not a "dead substance." The ancients believed that all matter responded to celestial influences. As it turns out, both water and silver are "ruled" by the moon. This is easy to prove to yourself when making colloidal silver. The best time to make colloidal silver is during the solunar period. There are two solunar periods each day. They begin approximately 6 hours after either moonrise or moon set, and last for about 90 minutes. Since these times change every day, you will have to figure out when these times are for your local area. Many metropolitan newspapers publish this data daily.
Free Software: solunar.com has free software that will give you the current day's times for the geographic center of all fifty states plus the Canadian provinces. When you follow all of these guidelines, your batches will be much more uniform, almost no black residue on the electrodes, and the bitter taste will be reduced or eliminated.
So, that's it! Making your colloidal silver during the solunar period gives you the best colloidal silver possible. It’s really quite easy.
