Recommended level max.: 50 mg/l nitrate in freshwater. • For approx. 50 measurements with glass cuvette. • For fresh- and saltwater with two different colour scales. • Colour scale with 11 colours from yellow to orange-red. • Measurement range from 1.0 to 240 mg/l nitrate. • Laboratory compensation system compensates water discoloration. • Includes syringe to measure amount of water. Product description The JBL Nitrat Test-Set NO3 is designed for the measurement and routine control of the nitrate content in saltwater and freshwater within the range 5-120 mg/l (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.: 50 mg/l nitrate in freshwater) Problem solutions Although nitrate (NO3) is non-toxic, it stunts the growth of fish and plants and leads to the excessive growth of algae in aquariums and ponds. Nitrate is only broken down by bacteria under anaerobic (oxygen-free) conditions. These occur, for example, in the floor covering material or in the reef rock of saltwater aquariums. Every filter which operates on normal biological principles produces nitrate. The nitrate consumption of plants is often not high enough, and nitrate becomes enriched in the water, leading to an increase in algae growth.
Measures against excessive nitrate levels in tap water: 1. Prepare tap water with JBL Osmose 120. This reverse osmosis removes about 90% of nitrates from tap water (at 25°C water temperature and a minimum pressure of 3 bar!). 2. Alternatively, tap water which has stood for a while can be pumped through a container with JBL NitratEX. By means of ion exchange, JBL NitratEX removes the unwanted nitrate. Measures against excessive nitrate levels in the freshwater aquarium: 1. Regular partial changes of water (approx. 1/3 every 2 weeks). 2. Prepare water with JBL Biotopol. 3. Measure nitrate content of tap water (max. 50 mg/l). 4. Either eliminate nitrate from the water using"
