I'm with Ron, don't know what machine you are using?
I can't speak for those "polarity reversal" machines but if it's not one of 
those then you need to remove electrodes front the water at regular timed 
intervals to wipe them clean before re-submerging them.
The low voltage will make the process take longer.  Again, don't know what 
machine you refer to regarding the 32 VDC?  My homemade machine runs on 24vdc 
and I get around 17-20ppm in 1 1/2 to 2 1/2 hours dependant on water room 
temperature.
Is the machine current limited or controlled?  If not then you will get current 
"runaway" which encourages all that gunk to develop.  The more silver 
dispersing in the water, the more conductive the water becomes and strips 
silver off electrodes quicker, it's an exponential thing.
That "gunk" is normal, but only if the electrodes are not removed and cleaned 
at regular timed intervals, or if the machine is not current controlled or 
limited, or if the machine hasn't the auto polarity reversal facility.
My machine does not have polarity reversal so I remove electrodes from water 
each and every 30 minutes to wipe them over, if they need it or not, then swap 
the electrodes over manually to change the polarity on the electrodes before 
re-submerging them.  As the process progresses however, the quicker that gunk 
will begin to form.
The silver hydroxide and oxide, the "gunk", I'll leave to the experts to 
explain, all I do is keep that to an absolute minimum.
The only reason for throwing the first batch away perhaps is due to any coating 
which may be on the electrodes from manufacture?  5 minutes brewing in mains 
water or rain water will get rid of that, then wipe electrodes clean and use 
only distilled water forever more.
Measuring ppm?  Any TDS or PWT or whatever meter will get you in the ball park, 
none are accurate for silver preparations but at least you will know when to 
shut the machine off at your desired ppm with every batch you make.  Meters 
won't indicate the particle content, hence they miss some silver content on the 
reading.  You will in all likelihood have more *total* silver content than any 
meter will indicate.

HiFrom this message with great questions - I have an additional question: how 
do I measure CS's ppm?

Hello. I have just made my first batch of colloidal silver with my new machine 
and I have some questions.  1.   The voltage is adjustable from 3.7 – 11.7 VDC. 
I was surprised that it would not go up to the 32 VDC that I have read about. 
Do you think that something is wrong?2.   If nothing is wrong, what would be 
the better voltage to set it at and why?3.   I ran the machine for 2 hours and 
got 7 ppm. Is that normal?4.   I continued to run it all night (about 14 hours) 
and got 15 ppm. Is that OK?5.   The negative silver wire is solid black. Is 
that normal?6.   The positive silver wire was covered with what looked like ¼ 
inch of brown jelly something? Is that normal?7.   The bottom of the jar was 
covered completely with about ¼ inch of the same brown what ever? Is that 
normal?8.   The CS itself is basically clear.9.   I will filter the CS through 
a coffee filter. Is that right?10.               I am supposed to throw away 
the first batch. Is that right? Floyd    Floyd
