User manual:

2. Add 5 NO2 reagent drops and mix well

3. Wait 5 minutes

4. Specify the NO2 value using the color tab.

Because nitrites are highly toxic to all marine life, its level in aquarium water should be zero. If the nitrite level is 0.5 mg / l, this means that there is no sufficient bacterial in water and then Colombo Marine Bacto is recommended. At the NO2 level 1mg / L, nitrites can become toxic and then 25% water change should be made and only then add bacteria.

The package is sufficient to perform 40 tests.
