Correct. The only issue really is the cost.
If you are going to have a large anode, say
3" X 6" of a heavier gage (area of 15 square inches
immersed, on one side) the cost may be around $70 US.
You may not want to invest in an equivalent silver
cathode of the same cost. Of course, you cannot do
polarity switching.
(I'm not absolutely sure what would happen if you put
the positive polarity on different metals, if you would
get ions from all of the metals or not... Although,
pacemaker cases [anode electrode] have been made out of
stainless steel and titanium. Presumably the stainless
alloy has no nickel. So, maybe you could use certain types
of stainless steel, certainly titanium.)

Evening Dan,
>The *Anode* (connected to the + terminal) needs to be silver.
>The *Cathode* (connected to the - terminal) can be another metal.
No metal is removed from the Cathode, Right?
Why not use a silver wire for the Cathode? How long will it last?
3 years or 5, or maybe 10.
Does the other metals make any better CS?
I use Silver wire for both electrodes. It makes not difference
which electrode I connect the positive to.
I simply do not see the big issue and concern of NOT using silver
wire for both electrodes.
What am I missing? Does Stainless or Copper help?
Seems enough people have trouble keeping up with positive and negative
anyway?
Plus, if anyone is obsessed with larger surface area, use 3, 5, or 19
pieces of silver wire.
