• Packaging content：You’ll receive 150 pieces of 16mm bio balls, perfectly sized for efficient biological filtration in aquariums, fish tanks, and ponds. The generous quantity ensures long-term use without frequent replacements.
• Eco-Friendly & Durable Materials：Crafted from high-quality plastic and sponge, these biofilter media are non-toxic, odourless, and water-safe. They won’t degrade or alter water chemistry, making them reusable and ideal for sensitive aquatic environments.
• Superior Bio-Filtration Performance：As water flows through the porous structure, nitrifying bacteria colonise the surface, extending contact time to break down harmful toxins (ammonia/nitrites). This promotes crystal-clear water and a healthier habitat for fish.
• Space-Saving & Versatile Design：The 16mm diameter fits seamlessly into filters (top, bottom, or pond filters) where space is limited. Their multi-faceted surface maximises bacterial growth, compensating for small filter compartments.
• Wide Aquarium & Pond Compatibility：Perfect for freshwater and marine setups, these bio balls are essential for tropical fish tanks, koi ponds, and sump filters. Easy to install—simply place them in your filter system for instant biochemical action.
