API Nitrate Test Kit measures Nitrate (NO3-) which is produced in the aquarium by the biological filter. Beneficial bacteria in the biological filter convert toxic ammonia and nitrite into nitrate. A high nitrate level indicates a build-up of fish waste and organic compounds, resulting in poor water quality and contributing to the likelihood of fish disease. In the opinion of many aquarists, maintaining a low nitrate level improves the health of fish and invertebrates.
