Nitrites are formed as ammonia is broken down. Toxic and potentially lethal to fish, they can quickly pollute the water and suffocate plants and fish.
API's Nitrite Test Kit is equipped to carry out 180 tests, and can be used in both fresh and salt water aquariums. The test can read levels between 0 and 5ppm.
The test works quickly to give you an accurate reading.
