JBL Nitrite (NO2) Test Kit Complete test kit contains: 1 nitrite test for approx. 50 measurements, incl. 2 reagents, 2 glass vials with screw caps, syringe, comparator block and colour scale. Refill Kit contains: one set of reagents NO2 Healthy aquarium/healthy pond with conditions close to natureThe right water values are dependent on the fish stock and the plants in the aquarium/pond. Even if the water looks clear it can be contaminated. With bad values diseases or algae can appear in the aquarium/pond. To maintain a healthy aquarium/pond with conditions close to nature it is important to check and adapt the water values regularly.For each water analysis JBL provides water tests in the form of quick tests or colour change tests. These determine a certain value or several values in one go. With these water tests you can recognise algae problems and negative nitrate, nitrite, potassium, magnesium values etc.Why test:Nitrite is produced when bacteria degrade protein and ammonium. It is normally processed further into non-toxic nitrate. In aquarium and pond water nitrite (NO2) should not be measurable. If nitrate is measurable, it is a sign that the bacterial degradation process has been disturbed. From a concentration of 0.4 mg/l onwards it is dangerous or even fatal for fish, because nitrite blocks the transport of oxygen in the blood. This can be remedied by water changes and good bacteria starters, such as JBL Denitrol and JBL BactoPond.Recommended nitrite values:Freshwater aquarium (community aquarium): 0-0.2 mg/lLake Malawi/Lake Tanganyika aquarium: 0-0.2 mg/lPlant aquarium with few fish (aquascaping): 0-0.2 mg/lMarine aquarium: 0-0.2 mg/lPond: 0-0.2 mg/l
