Local tap water is 120 ppm. Worth getting reverse osmosis in this case?

  1. Like the title says.

    Will I see much benefit from upgrading to a reverse osmosis system in this instance or would the gains be inconsequential?

  2. 120ppm is alittle high but not too bad, I'd say if your Ph is good then r/o water wil not make much difference .
  3. No, if you are under 200PPM you're GTG.
