The API Nitrite Test Kit helps you monitor nitrite levels in your aquarium. Nitrite forms as part of the natural nitrogen cycle, when beneficial bacteria break down ammonia from fish waste and uneaten food. Even low levels can stress fish, and high levels are harmful, affecting their ability to take in oxygen.

This kit reads nitrite from 0 to 5 ppm and suits both freshwater and saltwater aquariums. It’s especially useful when cycling a new tank, after adding new fish or when troubleshooting water problems. With 180 tests per kit, it’s an economical choice for regular monitoring.
