TM NO2/NO3 Test Professional

Nitrate ions (NO3-) are formed as the end product of nitrification from ammonium (NH4+). In the first partial stage of this bacterial process nitrite (NO2-) is formed, which is highly toxic, especially for freshwater animals. If the nitrification process is functioning, the nitrite is converted to the comparatively non-toxic nitrate in the second stage. In saltwater aquaria, increased nitrate concentrations lead to a disturbance of the growth of sensitive corals. A danger of high nitrate contents for all aquariums is the strong promotion of algae growth. In some reef aquariums, extremely nutrient-poor conditions are created - here, nitrate deficiency situations may occur. With the high-resolution Tropic Marin® Nitrite/Nitrate Test Professional the nitrite concentration can be determined with a particularly high accuracy in the low concentration range between 0 and 1 mg/l and a nitrate concentration between 0 and 20 mg/l.
