Step 1:

Measure Nitrate

  • Dip the strip into your water for 1 second and remove. Do not shake the excess water off.
  • Hold the strip level, pad side up, for 30 seconds.
  • At exactly 30 seconds, compare the color of the top pad to the color chart on your bottle labeled "Nitrate Nitrogen ppm."

Step 1:

Measure Nitrate

Things to remember:

  • Remove sunglasses before taking your reading.
  • The color will continue to change after 30 seconds, so record your value as close to 30 seconds as possible.
  • If your strip's color falls between two values, estimate an intermediate value.
