API Nitrate Test Kit
Quick, easy and accurate nitrate testing at home!
From the manufacturer:
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.
Contains 90 tests and includes 2 test solutions, easy-to-ready instructions, glass test tube and color chart
Full instructions included in each testing kit. Use in conjunction with NITRITE and AMMONIA tests!
