Easy to use and practical, this filter sponge is designed for use with aquarium filters to maintain peak water quality and fish health. The JUWEL Nitrax model (JU88055NET) is a biological filter medium that reduces nitrate levels through anaerobic breakdown, significantly decreasing algae growth. It contains special microorganisms that break down toxic metabolic products like ammonium and nitrite, reducing the risk of fish death and promoting fish vitality. Simply place the sponge in your filtration system under the carbon cushions, and replace it every 3-4 weeks or when filter output decreases. Ideal for PMDD aquarium setups, this product ensures a healthier aquatic environment. Always read the product description before use.
