I also won't entertain the idea of auto polarity reversal for the same reason 
Dave stated, but then I'm not a commercial enterprise.  If I was selling the 
stuff, then I would have to consider that option due to production volumes and 
time.  Something must go somewhere off those electrodes and the only place that 
'something' can go is back into the water, however, it won't be immediately 
observable due to that polarity reversal switching back and forth.  If they are 
not removed and cleaned at regular timed intervals to minimise that 'something' 
being dispersed in the water, then whatever comes off those electrodes will 
remain circulating in the water and end up at the bottom of the storage vessel 
after gravity has done its thing.

    Reversing polarity of the electrodes while making CS is an effective
    and widely used method of decreasing buildup of silver and oxides of
    silver on the electrodes.  I have made thousands of gallons of CS,
    and I reverse every minute, on a two minute cycle.  Reversing
    eliminates the dark oxides because the electrode which forms the
    oxide is exposed to monoatomic hydrogen during the next half cycle,
    and the hydrogen immediately reacts with the oxide reducing the
    silver oxide to silver.  Also any silver powder that accumulates on
    an electrode, either by reduction of silver oxide, or by deposition
    of silver from the solution, goes back out on the next half cycle as
    well.  The result is electrodes which stay amazingly clean and never
    need to be cleaned.  I can typically make several thousand gallons
    of CS on a set of electrodes and have never ever had to clean them.

    

    Also I have never witnessed any silver oxide coming loose due to
    polarity switching.  If any were to come loose it would be from the
    stirring of the water, not a polarity switch.

      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.

          I am considering using this to make
            colloidal silver. I like the idea of reversing polarity
            because it will slow down a build_up of CS near one
            electrode and both electrodes (hopefully) wear evenly. Also
            I have one of these around and it will save a bit for the
            time being :-)

            

            Are there any "cons (& pros)" to this notion. I would
            appreciate your thoughts on this. Thank you.
