Allows early detection of water quality problems. Encourages proactive aquarium maintenance. Ensures continued use of your existing NTL nitrite test kit. Understanding Nitrite Nitrite is produced when beneficial bacteria convert toxic ammonia into nitrite as part of the aquarium's nitrogen cycle. A second group of beneficial bacteria then converts nitrite into the much less harmful nitrate. While this is a normal biological process, any detectable nitrite is considered unsafe and should be addressed immediately. What to Do if Nitrite Is Detected 0.25–0.5 mg/L (ppm): Add a filter booster such as Filter Starter. 1.0 mg/L (ppm): Perform a 25% water change. Above 1.0 mg/L (ppm): Perform a 50% water change. Check other important water parameters, particularly ammonia and pH. Ensure your biological filter is functioning correctly. How to Use Ensure the test tube is clean. Fill the test tube with 5ml of aquarium water. Add 5 drops of the Nitrite reagent. Replace the cap and shake thoroughly. Wait 2 minutes. Compare the sample colour with the supplied colour chart. A colourless sample indicates 0 mg/L (ppm) nitrite. Any hint of pink indicates the presence of nitrite. Ignore any colour that develops after the initial 2-minute reading. Specifications Product: NTL Spare Nitrite (NO₂) Reagent Application: Replacement reagent for nitrite water testing. Suitable For: Freshwater aquariums. Test Type: Liquid reagent colour comparison test. Why Choose NTL Spare Nitrite (NO₂)?
