JUWEL Nitrax L – Green Nitrate-Reducing Sponge for Bioflow L and Bioflow XL Filters
JUWEL Nitrax L is a specialized filter sponge designed to reduce nitrate (NO3⁻) levels quickly and effectively, helping to prevent algae growth and maintain long-term biological stability in the aquarium. Compatible with JUWEL Bioflow L and Bioflow XL internal filters, this high-performance green sponge contains a concentrated blend of denitrifying bacteria that activate instantly upon contact with water, enhancing biological filtration from the very first use.
Its porous structure provides a large colonization surface, supporting continuous bacterial development and promoting efficient degradation of nitrogen compounds. This helps reduce unwanted nutrient buildup and prevents imbalances that may lead to algae outbreaks, cloudy water or stress for fish and plants. Suitable for both freshwater and marine tanks, Nitrax L is an essential component for aquarists seeking clean, stable and naturally balanced water conditions.
For optimal performance, the sponge should be replaced every 6 weeks. Installation and maintenance are simple, requiring no additional tools or complex procedures. JUWEL Nitrax L is particularly recommended for heavily stocked aquariums, community tanks or setups where superior biological filtration is essential.
