The EDTA will drop its Di-sodium and bind with the silver ions and particles, stabilizing and capping the silver... and basically become Silver-EDTA. EDTA destroys biofilms. You will find plenty of literature on bacteria such as Pylori and Biofilms online. EDTA will pull a magnesium, a calcium, an iron, or zinc from the the biofilm (and even from the bacteria themselves) and drop silver particles/ions in its place... directly targeting and killing bacterial colonies.
With my device, at 4-5 minutes the water starts to become discolored as the particles start to become larger. You may as I have to space the electrodes further apart which helps prevent larger particle precipitation. But larger particles also have their benefits. I find the larger size more useful cleaning the mouth and preventing biofilms on teeth.
I would recommend using Di-Sodium-EDTA and not Calcium-Di-sodium-EDTA... to avoid possible contamination of your silver suspension with calcium. EDTA's highest affinity is for calcium after all, which may affect the electrolysis process; also, because Calcium-EDTA it is already bound to a calcium it will have less affinity to bind to calcium in the biofilms within the body. I would recommend consuming this on an empty stomach to avoid the EDTA binding with other metals in food particles. The 'Di-Sodium' in Di-Sodium-EDTA increases electrical conductivity allowing current to flow more easily between the electrodes.
There are medical bandages that combine EDTA and colloidal silver to enhance the healing process. Silver-EDTA combo is also used by dentists for sterilizing root canals. Using this simple process, you can make an oral vesion easily and at home.
How much to add? My generator makes make about 6.6-7 oz of colloidal-silver. This requires only a pinch of EDTA to be effective. Depending on the quantity of water in your generator, may require more or less. Once it starts turning subtly black, you are precipitating larger nano particles rather than silver ions. To prevent that, cut the electrolysis time shorter. Experiment and see what works for you. I use bulk supplements di-sodium edta, for its great price.
