Salifert Nitrite Test Kit
Salifert Nitrite Test Kit has easy-to-follow instructions and straightforward, accurate results.
Nitrite is a substance that is toxic to fish and invertebrates.
It is a misconception that once a tank is through its cycle (first 3 or 4 weeks) that nitrite has vanished.
Many nitrite test kits suffer from interference by amines (such as naturally occurring and essential amino acids) resulting in a too-low measured value especially if the nitrite concentration is relatively low.
Nitrite is converted to nitrate in properly cycled aquariums. The thus formed nitrate is transformed into harmless nitrogen gas (=denitrification). This happens in areas deprived of oxygen within live rock and miscellaneous filter materials.
Before it can be transformed to nitrogen gas the nitrate is first converted back to nitrite. When for whatever reason this particular cycle can not be completed, toxic nitrite can be present in significant concentration and readily be detected by test kits that do not suffer from amine interference.
The Salifert Nitrite Test Kit can perform approx. 60 measurements.
Directions for use:
Add with the syringe 1 ml of water to the test vial.
Add to this 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 colour chart on a part of the chart which is white and compare the colours looking from the top. Read the corresponding nitrite content. The nitrite values are in ppm (mg/L) nitrite.
