• 🐟【Safe for all aquatic life】Our bio filter balls are made from 100% polypropylene, which is corrosion-resistant and age-resistant. The 3-inch diameter is ideal for outdoor koi pond filters or large tanks, and will not be dispersed by water flow.
• 🐟【Hollow Design】The pond filter media allows water to flow through unimpeded, while the components in the middle create a vortex as water flows through the bio balls, increasing oxygen content and effectively improving water quality. And the 3-inch size greatly increases the surface area, providing more space for nitrification and promoting the health of fish and plants.
• 🐟【Better Choice】Our bio ball filtration media has a smooth surface with no sponge in the middle, allowing most debris to pass through directly and preventing secondary pollution caused by debris buildup. Porous lava rock can become clogged with debris, reducing the surface area available for nitrification. Additionally, porous lava and similar products are heavy and difficult to move.
• 🐟【Easy Maintenance】Lightweight, wear-resistant, and reusable - Simply rinse with the original pond water.
• 🐟【Wide Application】Our orange bio-ball filter media is an ideal biological filter media for outdoor koi ponds, large canisters, water garden ponds, freshwater/saltwater aquariums, aquaponics systems, fish farms, fish hatcheries, high density aquariums, and large-scale aquatic systems.
• 🐟【Package Include】50 Count orange bio filter balls, No black mesh bag in the package.
