TM NO2/NO3 test

For the determination of the nitrite and nitrate concentration Nitrite ions (NO2-) and nitrate ions (NO3-) are formed from ammonium (NH4+) in the nitrification process. In the first partial stage of the bacterial process, nitrite is formed, which is highly toxic for freshwater animals. If the nitrification process works, the nitrite is converted to 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 rare cases, nitrate deficiency situations can also occur. Therefore, the nitrite and nitrate concentrations of the aquarium water should be checked regularly. With the Tropic Marin® Nitrite/Nitrate Test, a nitrite content of 0 to 2 mg/l and a nitrate concentration of 0.5 to 50 mg/l can be precisely measured using finely graduated colour scales.
