API Nitrate Test Kit 

High nitrate levels in your aquarium indicate a build-up of fish waste and organic compounds, resulting in poor water quality and an increase in algae growth. Contrarily, maintaining a low nitrate level improves the health of fish and invertebrates.

Use the API Nitrate Test Kit to ensure that the nitrate levels in your tank are safe and healthy for your fish. The Nitrate Test Kit reads parameters from 0 to 160 ppm and may be used for both fresh and saltwater aquariums.
