Tropic Marin Nitrite/Nitrate-Test PRO

Tropic Marin Nitrite/Nitrate-Test PRO Freshwater / Saltwater For high precision determination of the nitrite and nitrate concentration

Nitrate ions (NO₃^–) are produced from ammonium (NH₄⁺) during the nitrification process. In the first stage of this bacterial process, nitrite (NO₂^–), which is particularly toxic to freshwater species, is formed. If the nitrification process is functioning properly, nitrite is then converted into the much less harmful nitrate in the second stage.

Elevated nitrite levels above 0.05 mg/l (ppm) are often observed in tanks that are still maturing or in those equipped with nitrate filters. Nitrate concentration can significantly impact the quality of aquarium water: high nitrate levels in saltwater tanks can inhibit the growth of delicate corals. Additionally, a surge in algae often accompanies high nitrate levels. Some reef aquariums maintain ultra-low nutrient conditions, which can lead to nitrate shortages. Therefore, it is essential to regularly test the nitrate concentration in aquarium water.

For freshwater aquariums, it is recommended to keep the nitrate levels below 50 mg/l (ppm), while for saltwater applications, the concentration should not exceed 20 mg/l (ppm). When caring for hard coral, the goal is to maintain nitrate levels below 10 mg/l (ppm). The ideal lower limits for nitrate will vary depending on the overall conditions of the aquarium.

With the high-resolution Tropic Marin Nitrite/Nitrate-Test Professional, you can measure nitrite and nitrate concentrations with exceptional accuracy in low concentration ranges: from 0 to 1 ppm for nitrite and from 0 to 20 ppm for nitrate.
