Tetra Test NO2


Tetra Test NO2 provides accurate and dependable results when measuring the Nitrite content of fresh and salt water aquaria.


As fish waste and food remnants in the tank decompose, toxic Ammonia is first generated, before transforming into Nitrite and later into Nitrate (Nitrogen Cycle). If the Nitrite level (NO2) is higher than 0.3 mg/l your fish can be exposed to long-term harm. This testing product is particularly helpful when constructing a new aquarium; included in the package are enough materials for 45 tests.
