API Nitrate Test Kit

Nitrate build-up in aquarium is often an indicator of declining water quality. High levels of nitrate are frequently associated with poor fish, health, algae growth, and a build-up of organic pollutants. Nitrate is produced in the aquarium by the biological filter. Beneficial bacteria in the biological filter converts toxic ammonia and nitrite into nitrate. A high level indicates a build-up of fish waste and organic compounds, resulting in poor water quality and contributing to the likelihood of fish disease. Excessive nitrate also provides a nitrogen source that can stimulate algae blooms.

The Nitrate Test Kit is a fast, easy and accurate test for freshwater and saltwater aquariums. The kit contains two dropper bottles for accurate dispensing of test solutions, easy-to-read instructions and color chart, a non-staining glass test tube with a snap-tight cap, and instructions.

Size:  Each bottle: 1 fl oz.

Available only to the continuous 48 United States via ground shipping methods.

Directions for testing Nitrate:

1. Fill a clean test tube with 5 ml of water to be tested (to the line on the tube).
2. Add 10 drops from Nitrate Test Solution Bottle #1, holding dropper bottle upside down in a completely vertical position to assure uniformity of drops.
3. Cap the test tube and invert tube several times to mix solution.
4. Vigorously shake the Nitrate Test Solution Bottle # 2 for at least 30 seconds. This step is extremely important to insure accuracy of test results.
5. Now add 10 drops from Nitrate Test Solution Bottle #2, holding dropper bottle upside down in a completely vertical position to assure uniformity of drops.
6. Cap the test tube and shake vigorously for 1 minute. This step is extremely important to insure accuracy of test results.
7. Wait 5 minutes for the color to develop.
8. Read the test results by comparing the color of the solution to the appropriate Nitrate Color Card (choose either Fresh water or Salt water). The tube should be viewed in a well-lit area against the white area of the card. The closest match indicates the ppm (mg/L) of nitrate in the water sample. Rinse the test tube with clean water after use.
