Not quite sure where to start with this one so ill ask here and hopefully get some response....so a test of my water in a digital meter says i have 170 ppm so 170 times 10 =1700 ......straight tap water....am i not using the meter right? I dipped it and swished it around for about 30 seconds...is a reading of 1700 even possible?
