  uS is the symbol for Microsiemens as conductivity per cubic centimeter
of  a liquid, used by conductivity meters. [ALL meters are conductivity
meters]
 
  Silver comes off the electrodes as conductive ions and some of it
converts to nonconductive forms over time [ "colloids" aka "particles" ]
that meters won't register.
  Therefore, a meter reading drops over time without the water losing any
silver.
