Salifert Profi Test Kits for reef, marine and advanced freshwater aquarists are some of the most precise and accurate test kits on the market. Kits are available for all aspects of the aquarium's chemistry, covering organic and inorganic pollutants as well as valuable marine trace elements to allow for accurate dosing when additives are required.
Nitrite is a substance that is toxic to fish and invertebrates. Many nitrite test kits suffer from interference by amines 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.
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. It probably is the most sensitive, accurate and fastest nitrite test kit available. The kit can perform approx. 60 measurements
