TetraPond Nitrite (NO2) Test Kit For Pond Water

The TetraPond Nitrite Test Kit allows for simple and accurate measuring of nitrite levels in your pond.Fish waste, uneaten food and dead plants in your pond are decomposed during the nitrogen cycle. The decomposition of this waste first produces ammonia, ammonia turns to nitrite and finally the nitrite turns to nitrate. If the nitrite levels in your pond are above 1.6 mg/l for extended periods of time this is harmful to fish.Includes 25 Tests
