Tests for nitrite in freshwater & saltwater aquariums. Toxic nitrite is produced by nitrifying bacteria in the biological filter as it breaks down ammonia. This kit tests for harmful nitrite and measures levels from 0 to 5.0 ppm. 100 tests per kit.
Nitrite (NO2-) is produced in the aquarium by the biological filter. Beneficial bacteria in the biological filter convert toxic ammonia into nitrite (also toxic). The biological filter then converts nitrite into nitrate (NO3-). Testing for the presence of toxic nitrite is essential, so that once detected, steps can be taken to remove it. Otherwise, nitrite in the aquarium will prevent fish from carrying on normal respiration. High levels of nitrite quickly lead to fish death. Even trace amounts of nitrite stress fish, suppressing their immune system and, thereby, increase the likelihood of disease and subsequent fish loss.
This test kit reads total nitrite (NO2-) level in parts per million (ppm) which are equivalent to milligrams per Liter (mg/L) from 0 ppm to 5.0 ppm, in either fresh or saltwater aquariums. Other nitrite test kits that measure “nitrite-nitrogen” (NO2-N) will give readings 3.3 times LESS than this test kit.
Instructions
- Fill a clean test tube with 5 ml of water to be tested (to the line on the tube).
- Add 5 drops of Nitrite Test Solution, holding dropper bottle upside down in a completely vertical position to assure uniformity of drops added to the water sample. Cap the test tube and shake the tube for 5 seconds.
- Do not hold finger over the open end of the tube, as this may affect test results. Wait five minutes for the color to develop. Read the test results by matching the color of the solution against those on the color card
