I installed a nice water filtration system with cataylic carbon, reverse osmosis, and deionization.
I bought a $15 TDS reader from amazon. My unfiltered tap water has TDS of 398 ppm, and my filtered tap water has a TDS of 0. (Incidentally, the RO only gets it down to 80ppm TDS, and the DI takes it all the way down to 0).
Last year I bought the water test from Ward labs, and I just bought another one to test my water.
However, if a TDS reader shows 0 ppm, does that imply:
- 0 ppm Sodium
- 0 ppm Potassium
- 0 ppm Calcium
- 0 ppm Magnesium
- 0 ppm CaCO3 (total hardness)
- 0 ppm Chloride
- 0 ppm Sulfate
I'm curious if I even need to do a test from Ward Labs given my TDS reader is 0 ppm.
