For the GH test kit, the directions are easy.
  • remove from main carton
  • throw it in the trash


The KH test kit is a little bit more involved.
  • remove from main carton
  • remove vial and fill with test water to the white line (5mL)
  • put in one drop of KH reagent, put on cap and shake
  • if it changes color, stop. This is 1 dKH or 17.86 ppm.
  • if it doesn't change color, continue adding one drop at a time, capping and shaking each time until the color changes
  • Let's say that it changes color after 4 drops. This is 4 dKH or 71.44 ppm.
