High nitrate levels in your aquarium indicate the accumulation of fish waste and organic compounds, leading to poor water quality and increased algae growth. Conversely, maintaining a low nitrate level improves the health of fish and invertebrates.

Use the API® NITRATE TEST KIT to ensure that nitrate levels in your aquarium are safe and healthy for your fish.

The nitrate test kit reads parameters from 0 to 160 parts per million and can be used for both freshwater and saltwater aquariums.

Contains 90 tests and includes two test solutions, easy-to-read instructions, a glass test tube, and a color chart.
