Salifert Nitrate Test Kit

Precision nitrate test kit ideal for sensitive reef aquariums. Maintaining a very low nitrate concentration of less than 1 ppm is essential for coral and invertebrate health. Salifert Nitrate Test Kit boasts a nitrate detection range starting as low as 0.2 ppm. Both serious reef aquarists and beginning saltwater hobbyists will find the Salifert Nitrate Test extremely easy to use. The Salifert Nitrate Test Kit does not suffer from amine interference for quick and reliable measurement of nitrate-nitrogen. 50 tests. Saltwater aquarium use only.

Low range: 0.2 - 10 ppm
Medium range: 2 - 100 ppm

Procedure for both ranges:

• Fill test vial with 1 mL of water.
• Add 1 level scoop of NO3-1 powder (compress this powder against the inner side of the powder container).
• Add 1 level scoop of NO3-2 powder and swirl gently (do NOT shake) for 30 seconds.
• Let it stand for 3 minutes.

Color comparison:

For Medium Range:
Place the test vial on the white portion of the color chart. Compare colors looking from the TOP. Use diffused daylight when comparing colors.

If the color corresponds to a value lower than 10 mg/L nitrate then it might be better to compare colors as shown for the low range (see below).

For Low Range:
If the medium range color comparison procedure gave a reading lower than 10 mg/L then you can use the low range procedure to increase accuracy.

The color for the low range procedure has to be compared by looking through the SIDE of the test vial.

The white portion of the color chart has to be held firmly against the side of the test vial. Use diffused daylight when comparing colors.

By looking through the side, the color is amplified by approximately 10 fold. For this reason, you have to divide the color chart values by 10. For example 2 will become 0.2 and 50 will become 5.
