C.C. SILVER & GOLD, INC. in Phoenix (online) sells 99.99 FINE SILVER 14 gauge silver wire, get a foot, cut in two pieces. Then get three 9 volt battery clips from Radio Shack and 3 batteries and hook them up red to black, hook the free black and the free red end of this daisy chain to alligator clips, keep silver wire tips parallel by sticking about 1/2 inch
through rubber or wood mount of some kind 3/8" apart, hook clips above mount, and keep mount bottom with the 5.5" of wire sticking out 1/2 inch
away from pure, distilled water in brown plastic or glass (non-metallic) container and in three minutes you can MAKE YOUR OWN! Clean electrodes with plastic scrubber, rinse and repeat to make gallons. Do not add salt to speed up reaction as it contains contaminants. It's fresher and purer than health food store silver colloid per info from one chain that had tests run and found quality uneven and heavy metal contaminants (Wild Oats). Keep the alligator clips out of the water or you'll have contaminants, too. Use environmentally (to clean defroster tray in fridge for example), topically or internally. If used internally, take N-Acetyl Cysteine to form Glutathione as Glutathione is used up with silver colloid use as it is a powerful oxidant that oxidizes bugs and parasites
in one-celled stage to death. Get an extra 6" of 9999 FINE SILVER wire to put inside tank water filters to keep the slime off. God bless and tell a friend!
