Ditto here.  My unit is a Colloid Master, which reverses polarity on a set 
schedule.  My EIS is always crystal clear, with no residues, and minimal 
discoloration of the electrodes.

I cannot see this.  My Puppy has reverse polarity and I don’t get any dark 
oxides forming—quite the reverse in fact.  dee

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.
