Nitrite Test Kit

The Salifert Nitrite Test Kit measures the extremely hazardous nitrite levels that build up in aquariums due an interference in the nitrogen cycle. Nitrites are typically converted into nitrates and removed throughout the nitrogen cycle, but when the cycle cannot be completed, these nitrites begin to build up and cause damage to the inhabitants of your tank. Unlike other nitrate testers, the Salifert Nitrite Test Kit is not impacted by the presence of amines. Even the most minute traces of nitrite will be detected with a noticeable color change to the testing kit.

Nitrite is a substance that is toxic to fish and invertebrates.

It is a misconception that once a tank is through its cycle, (the 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 too low measured values, especially if the nitrite concentration is relatively low.

Nitrite is converted to nitrate in properly cycled aquariums. The 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 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.

Salifert’s Nitrite test kit does not suffer from amine interference due to a proprietary formula.

Salifert’s formula results in a full color development within minutes. The developed color is intense, making detection of even minute traces of nitrite very easy. The Salifert Nitrite test might be the most sensitive, accurate, and fastest nitrite test kit available!
