  • Fill the test tube with water to 5ml
  • Pour one drop at a time (and count them) from the liquid into the water until it changes from red to green. Once the water turns green, stop pouring drops of liquid.
  • Each drop is equal to 10ppm (1ºf in French degrees)

101 - 300 ppm - hard

301 - 500 ppm - very hard
