API Nitrite Test Kit - Freshwater and Saltwater - 180 Tests

Nitrite, a major cause of fish death, is produced in the aquarium by fish waste and overfeeding. Even low levels affect the red blood cells of fish, reducing their ability to carry oxygen, thus causing suffocation and even death.

The Nitrite Test Kit is fast easy and accurate for freshwater or marine aquariums.
