Same here,  Ive used a silver puppy for years and its always been nice and 
clear.  On occasion I do have to clean the silver rods, but nothing serious.

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.
