Description
The jewel Nitrax reduces nitrate in your aquarium and leads to a significant reduction of algae growth. Nitrax is a biological filter medium and contains special microorganisms to break down toxic metabolic products (ammonium / nitrite) in your aquarium. This reduces the risk of fish dying. Nitrax also reduces algae growth through the anaerobic degradation of nitrate and thus promotes the vitality of your fish.
