API Nitrite Test Kit AQP26

Why Test For Nitrite?
The presence of nitrite indicates possible over-feeding, too many fish, or inadequate biological filtration.
Nitrite (NO2) is produced in the aquarium/pond by the biological filter. Beneficial bacteria in the biological filter convert ammonia into nitrite. The biological filter then converts nitrite into nitrate (NO3). Nitrite in the aquarium/pond is toxic; it will prevent fish from carrying on normal respiration, and high levels will quickly lead to fish death. Even trace amounts of nitrite stress fish, suppressing their immune system and increasing the likelihood of disease. Too many fish, as well as uneaten fish food and decomposing plants and other organic matter can cause excessive nitrite levels. Water should be tested for nitrite every other day when the aquarium/pond is first set up, and once a week after the biological filter has been established (in about 4 - 6 weeks).
Testing Tips: This test kit reads total nitrite (NO2) level in parts per million (ppm) which are equivalent to milligrams per liter(mg/L) from 0 - 5.0 ppm (mg/L
