Tetra NitrateMinus naturally reduces the algae nutrient nitrate (NO3-). By activating nitrifying microorganisms, excessive nitrate levels can be reliably reduced and water quality improved.


  • The granules contained activate microorganisms that feed on nitrate and thus biodegrade it.
  • For better water quality
  • For all fresh and salt water aquariums
  • 100 ml for 400 litres of aquarium water
  • 250 ml for 1.000 litres of aquarium water


Shake well before use.
Add 2,5 ml to 10 l aquarium water weekly. The visible active ingredient granulate spreads in the aquarium and slowly sinks to the bottom. Tetra NitrateMinus is absolutely harmless to aquarium inhabitants and plants. To check the nitrate level (NO3-) in the aquarium, you can use the Tetra Test 6in1 or the Tetra Test NO3-, for example.



The orientation of Tetra (founded in 1951), one of the most traditional and at the same time most innovative companies in the landscape of German aquaristics, goes far beyond the production of feed for aquarium inhabitants. The perfect interplay of research and quality ensures the highest grades, even according to the IFS standards. Beside of the well known TetraMin or the popular water care products, Tetra offers complete aquarium sets and modern cabinets in 120 countries around the globe. Tetra has been shaping and influencing the modern world of aquaristics for over 70 years with its innovative strength like hardly any other company.
