Why analyse Nitrite? Nitrite can create a big problem for fish when concentrations are high. Nitrite affixes to the Hemoglobin molecule and inhibits Oxygen transport in the blood. A concentration up to 0.3mg/l is considered potentially dangerous.
Where does Nitrite come from ? Nitrite is generated through Ammonia oxidation by nitrifying bacteria such as Nitrosomonas. Generally, high concentrations of Nitrite are observed when a newly set up aquarium is going through the cycling process. Full biological establishment of a new aquarium will commonly occur in approximately one month. In saltwater environments this time can be almost doubled. When the aquarium is fully established, no Ammonia and Nitrite should be present. A sudden spike in the Nitrite usually signals a dangerous imbalance in the system.

Evaluating the results
Cycling on new systems
Results above 0.3mg/L NO2
In start up conditions, it is common to see high levels of nitrate. The bacterial strains responsible for nitrification (transformation of ammonia to nitrite and finally to nitrate) are not available in a new aquarium set-up. It is strongly recommened to use a biological aquarium supplement in order to accelerate the bacterial growth and nitrification process.
Established systems
If the result is close to 0.3mg/L NO2,
This indicates a safe level of nitrate. However, you should test again 24 hours later. If the level of Nitrite is above 0.3mg/L, then this indicates that the Nitrite level is rising and this is probably the result of the presence of dangerous levels of ammonia. If this is the case, we recommend that you perform an Ammonia test on you water to deal with the ammonia problem. Add a dobule dose of bacterial aquarium supplement to ensure that adequate levels of befeficial bacteria become rapidly available.
If the result is above 0.3mg/L NO2
A dangerous amount of Nitrite is present in the water. Immediatly change 20% of the water. Use Water Ager in the replacement water to reduce fish stress, remove Chlorine and Chloramine and neutralize heavy metals. Add replacement water slowly to avoid fluctuations in other water characteristics. Add a double dose of bacterial starter to activate and supplement the bioloical filter. Use of aquarium salt at recommeneded package instruction; dosage can reduce the toxicity of nitrate.

Instructions
1. Fill test tube to the 5ml line with water to be tested.
2. Add 5 drops of reagent #1 and 5 drops of reagent #2 into test tube. Insert cap
hold with finger and shake well to mix. Attention! always use the cap, Avoid skin contact.
3.
Wait 2 minutes for colour to develop, shake again, and match the test colour to the closest colour on the test
chart.
4. After use, rinse the tube with fresh tap water to ensure it is clean for next use.
