Do you use the reverse polarity with the SP?  This is what I do and I never
get any black stuff.  I only use paper towel to wipe the electrodes clean. 
Do you check your distilled water before each use?  I use a TDS meter and
check mine before and after I have made the CS.  The only time I got yellow
CS was the fault of the plastic bottles I put it in.  When I corrected this,
my CS is more or less, the same.  Ken sometimes doesn't get his mail on one
of his numbers, but I think Mike may have his other number. dee

Subject: CS>Silver Puppy
 
I am new to CS, having made 7 1-qt batches with a Silver Puppy. The first 4
batches were clear; the next two had large particles floating on top and at
the bottom of the jar. The last one was very yellow.  I used room temp
distilled water and used the same process for each.  I did wipe the silver
electrodes clean between batches with a slightly abrasive cloth. I emailed
the company with no response. I need to get a supply made up!  Can someone
tell me what the problem might possibly be?  Thank you for any help!
