Use the API Nitrate Test kit to monitor Nitrate levels in your aquaponic systems and fish tanks. 90 Tests, colour chart and easy to read instructions. High Nitrate levels can lead to poor fish health.
Why Test for Nitrate?
Nitrate (NO3–) is produced in the aquarium by the biological lter. Bene cial bacteria in the biological lter convert toxic ammonia and nitrite into nitrate. A high nitrate level indicates a build-up of sh 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 sh 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 make sure the nitrate does not reach an undesirable level.
