Nitrite ions (NO2) are created from Ammonia through a known process called Nitrification or the Nitrogen Cycle. It is the bacteria that convert Ammonia into Nitrite and then into Nitrate by oxidation. This process can take 3-4 weeks.
In seawater, NO2 levels should not be detectable by this test. Levels above 0.05 PPM are dangerous and not acceptable.
Royal Nature 's new Nitrite test kit can be used in both freshwater and saltwater aquariums. This kit makes it possible to determine the concentration of nitrites in a range of values going from 0.1 to 5 mg/L with a very precise color scale.
The Nitrite Royal Nature test kit has been designed to be easy to use, read and offers the possibility of carrying out 100 tests per kit.
Royal Nature has spent time making this kit to be accessible, but also to make it easier to read and more accurate. The biggest criticism of titration test kits is their reading mode, which makes the process uncertain. So the color variation is important for many factors, like the ambient light, the way of doing the sampling or the individual visual perception of the colors.
Royal Nature wanted to take its time, to draw inspiration from scientific studies to make a measurement scale with colors adapted to general visual perception.
The Nitrite Royal Nature test kit is used using a powder and requires only one step.
This test measures NO2 levels within the following ranges of values 0.1 – 0.3 – 0.5 – 1 – 3 – 5.
