"JBL Nitrite Test-Set NO2
Recommended level max.: 0,1 mg/l nitrite in freshwater.
• For approx. 50 measurements with glass cuvette.
• For fresh- and saltwater.
• Measurement range from 0.025 to 1.0 mg/l nitrite.
• Colour scale with 9 colours from yellow to pink.
• Laboratory compensation system compensates water discoloration.
The JBL Nitrit Test-Set NO2 is designed for the measurement and routine control of the nitrite content in saltwater and freshwater within the range 0.025-1.0 mg/litre (ppm). The compensation method developed specially by JBL allows precise and reliable results to be obtained even in moderately discoloured aquarium water, e.g. caused by peat filters and disease treatment (Recommended level max.: 0.25 mg/l NH4)
Where comes nitrite in aquariums from?
Nitrite (NO2) is a strong poison which blocks the transport of oxygen by the blood and leads to internal suffocation. It is formed by bacterial decomposition from ammonium and is further broken down into the non-toxic nitrate NO3. If nitrite levels exceeding 0.1 mg/l are measured, the bacterial break down of nitrogen is seriously damaged, without any doubt. This may be the result of treatment with antibacterial medications.
Measures against excessive nitrite levels in a freshwater aquarium:
1. Major water change of 1/3 to ½ the content of the aquarium.
2. Preparation of the water with JBL Biotopol.
3. Activate filter with JBL Filterstart.
4. Add JBL ClearMec plus to the filter. This filter material removes nitrite and nitrate from the water.
5. Identify cause: quantity of feed, fish stocking level, use of medications etc.
Measures against excessive nitrite levels in a saltwater aquarium:
1. Change 1/3 water.
2. Preparation of the water with JBL BioMarol.
3. Identify cause of nitrite: remove dead fish, clean areas of pollution, check filter etc.
4. Prime filter biologically with JBL Filterstart."
