The idea of reversing polarity during the manufacturing process is a very
bad idea and obvious design flaw. Far better to select one electrode, and
make a mark at the top with a pair of pliers, then simply connect it to
positive one run , then negative the next, keeping note of dates you use
the marked electrode with neg or pos current.

The reason for this is that you will accrue a large amount of dark oxides
which should not be disturbed during manufacturing. If they get into the
sol (colloid) then the ions coming of the electrode will then stick
to those chunks and your sol will bottom out much quicker, the particles
also being less therapeutically beneficial as they will be getting so large
to the point where they will just not be able to pass inside cell tissue
and kill pathogens, also creating more possibility
of argyria skin discolouration, though that can be lessened or even removed
with selenium supplementation to chelate it from the skin I read. The
regular changing of polarity will just push a load of muck into the
distilled water and act as a magnet for the smaller groups of ions to stick
to.

With best wishes, Dave
