Important information

Safety Information

Please Read Instructions Before Use

Ingredients

hydrochloric acid

Directions

Nitrate 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. Maintaining a low nitrate level improves the health of fish and invertebrates. Excessive nitrate also provides a nitrogen source that can stimulate algal blooms. Aquarium water should be tested for nitrate once a week to ensure the nitrate does not reach an undesirable level. This test kit reads total nitrate (NO3) level in parts per million (ppm) which are equivalent to milligrams per liter from 0 – 160 ppm.
