The Tetra NitrateMinus Pearls serve for permanent reduction of the nitrate content when setting up a new aquarium. With nitrate, the aquarium is deprived of an important nutrient that the algae can quickly utilise. The water quality is improved in the long term and the maintenance effort is reduced.


  • Purely biological nitrate reduction for 12 months
  • Long-term improvement of water quality
  • Algae growth is significantly reduced
  • Simple application by incorporation into the substrate
  • Blends in visually with the substrate and is continuously broken down by bacteria
  • Permanent reduction of the nitrate value below 40 to 50 mg/l (depending on the aquarium conditions)
  • Re-dosing every 12 months
  • Higher doses (up to double the amount) can be added at any time to increase the effect.
  • In granule form
  • Suitable for fresh and seawater aquariums


8 g Tetra NitrateMinus Pearls per 10 litres of aquarium water (one level capful for 30 litres of water). Distribute Tetra NitrateMinus Pearls evenly over the bottom and work it into the gravel as far as possible. Completely re-dose every 12 months. If nitrate levels rise within the 12 months, a top-up can be added.
