In a properly cycled aquarium, nitrite is converted to nitrate and then, if there are areas deprived of oxygen such as in live rock and other filter materials, this nitrate is converted back to nitrite and then transformed into harmless nitrogen gas. If this cycle breaks down then nitrites, which are extremely toxic to fish and invertebrates, can form in high concentration. Can be used for marine water, frewshwater and garden pond water. Many nitrite test kits suffer from interference caused by amines e.g. naturally occurring and essential amino acids. This can result in a too low measured value, especially when the nitrite concentration is relatively low. Because of its unique formulation, the Salifert Test Kit does not suffer from amine interference, and offers full color development within one minute. Also, the color is very intense making the detection of even minute traces of nitrite easy. The test kit has two different scales: an ultra-low scale for nitrite-nitrogen which ranges from 0.002 - 0.12 mg/L, and a medium scale for nitrite-nitrogen which ranges from 0.02 - 1.2 mg/L. Sufficient for 50 tests.
- Add with the syringe 1ml of water in the test vial.
- Add to 1 level spoon of the NO2 powder. Swirl the contents of the test tube gently for 20 seconds. Allow to stand for 3 minutes.
- Place the open test vial on top of the color chart on a part of the chart which is whiteand compare the colors looking from the top. Read the corresponding nitrite content. An intermediate color corresponds to an intermediate nitrite content.
