DescriptionProduct DescriptionTetra NitrateMinus Reduces the algae nutrient nitrate in a natural way. Tetra nitrate minuses has been shown to reduce the nitrate content in the aquarium below 40 to 50 mg/L and keeps it at a relatively low level. Due to this permanent reduction of nitrate, an important nutrient is deprived of algae, so that unfavorable living conditions are created and the algae can grow poorly. The aquarist can look forward to a clear aquarium and an unobstructed view of the fascinating underwater world.DirectionsApplication: Shake well before use. Add 2 ml of product per 10 litres of aquarium water once a week. Visible particles slowly spread and sink. Tetra NitrateMinus is totally harmless to aquarium flora and fauna. Check the nitrate values (NO3-) in the aquarium, e.g. with Tetra Test 6in1 or Tetra Test NO3-. Use Tetra NitrateMinus when values are too high.
