Hi I have a TDS meter and not sure about how I am using it. I put it in my CS jar and I wasn't getting anything just o I was wondering how long I have to leave it and how deep I was told to stir it I got a meter because my CS seems so clear I can't see any particles in it when I was 1st using it for a couple of yrs I did get particles from it and black stuff I don't get really anything I am worried because I have a sick dog and I'm giving her a lot Appreciate some help Carrole
