I've always had my Colloid Master switch set to  standard.  I rinse my quart 
jars over and over and then rinse them  again with distilled water.  I scrub 
the silver wires and rinse  them with distilled water too.  Some batches I heat 
distilled  water to almost boiling and add a little CS before starting it and 
it  only takes about 1 1/2 to 2 hours at 5.5.  If I start cold, I  still add a 
little CS, just about a couple tablespoons maybe, and it  takes many hours, but 
I end up with the same results.  The  instructions said to strain it after 3 
days in coffee filters and I  just get a small amount of gray sediment (silver 
oxide?).  That  first batch I made at 8 settled out a bit and became yellow 
after  several days passed.  Does everyone get the gray sediment at the  bottom?
