JUWEL Nitrax reduces the nitrate in your aquarium and significantly reduces algae growth. Nitrax is a biological filter medium and contains special micro-organisms for the breakdown of toxic metabolic products (ammonium/nitrite) in your aquarium. This reduces the risk of fish kills. In addition, Nitrax reduces algae growth through the anaerobic breakdown of nitrate and thus promotes the vitality of your fish.

Features of JUWEL Nitrax:
• Reduces nitrate
