NO2/NO3 Nitrite/Nitrate Tropic Marin Sweet and marine 50 tests

For high precision determination of nitrite and nitrate concentration

Nitrate ions (NO3–) are formed by ammonium (NH4 +) as a final product of the nitrification process. Nitrite (NO2–), which is highly toxic in particular for fresh water species, is produced in the first phase of the bacterial process. If the nitrification process works, nitrite is converted into relatively non-toxic nitrate in the second phase. Increased levels of nitrites exceeding 0.05 mg/l (ppm) are usually found in reservoirs during maturation or in reservoirs with nitrate filters.

Nitrates affect water quality in the aquarium: higher concentrations of nitrates in marine aquariums will inhibit the growth of delicate corals. Algal flowering is often the result of a high level of nitrates in an aquarium. Some barrier aquariums have extremely low nutritional conditions: in cases such as these nitrate deficiencies may occur. Therefore, the concentration of nitrates in aquarium water should be tested regularly. It is recommended to maintain nitrate concentration in fresh water aquariums below 50 mg/l (ppm), while the concentration should not exceed 20 mg/l (ppm) in salt water applications. When you grow hard coral, the goal is to maintain nitrate concentration below 10 mg/l (ppm). The lower limits for nitrates depend on the general conditions of the aquarium.

With the Tropic MarinHigh resolution ® Nitrite / Nitrate-Test Professional can determine nitrite and nitrate concentrations with a particularly high accuracy in the low concentration range between 0 and 1 ppm for nitrites and between 0 and 20 ppm for nitrates.
