Not to nitpick but silver DOES NOT dissolve in water. Whatever this guy's end 
result is by ''dissolving'' silver in his ''tap'' water has no relationship to 
colloidal silver.. Also, if one is plating the inside of their ''colloidal 
silver jar'' there is something out of whack with they're generator 
system....it reeks of runaway current. Folks like Ode Coyote with his 
SilverPuppy and Trm Williams with his Silvergen CS generator have done their 
homework and put out a great unit..  Also, cleaning your silver rods/strips 
should NOT be a trying effort. A paper towel or a soft clean cloth works 
well...and quit trying to make whatever ''residue'' they might leave behind is 
an issue...It's a NON issue unless you make it one..
