Can I jump in here?  We use 7/16 to 1/2 inch spacing on our SG7 Pro.  With the 
electrodes that close together the current gradient between plates is pretty 
strong right at startup and we reach current limiting very quickly.  However 
the water has to be moving fairly rapidly or the unit will shut down because it 
senses voltage drop across the electrodes to control the shutoff point.  We use 
a submergible fountain pump to keep the water moving vigorously.  The idea that 
it takes very slow water movement to produce good CS doesn't have any effect on 
our generator.  It produces particle size in the general range of .001 to .005 
microns.  

So, I think closer is better if you can keep the water moving.  Why have to 
wait to get up to speed?

My 2 cents.

Regards,

Trem Williams

  Hi Ole Bob,

  Wouldn't spacing the electrodes farther apart be a "good thing" if you were 
producing a couple of gallons at a time and your power supply was set up to 
compensate for it? It seems to me that it might speed things up a little. Does 
a slow start (low voltage) or a fast start (higher voltage) make a difference 
if the final current is limited?

  Hi Andy,

  The current drops down and it takes longer to get to the current
  limiting level.
