CS>making cs

[Revonda Henderson]

When I make a batch of CS I always clean the silver electrodes before brewing. 
However, when the batch is complete there are usually a few silver particles or 
sluggy type substance floating in the water. So, I tried straining the cs 
through a reuseable coffee filter to get these particles I can see out. My ppm 
meter reads around 5 when the batch is complete but after I strained it the ppm 
meter reads 0. Any advice please...Thanks
