Bio Balls are high-performance biological filter media designed to support beneficial bacteria and improve water quality in ponds and filtration systems. Their unique geometric design provides excellent surface area for bio colonies to grow, helping convert harmful fish waste and organic debris into safer nutrients that support a balanced aquatic environment.
Each 1.5-inch Bio Ball provides over 18.2 square inches of surface area, allowing efficient biological filtration in gravity waterfall filters, pressurized pond filters, and other filtration systems. Unlike traditional media such as lava rock, Bio Balls resist slime buildup and maintain strong performance with significantly less maintenance.
Constructed from durable high-density polypropylene, Bio Balls are lightweight, long-lasting, and will not degrade over time. Their spherical peg design allows them to pack efficiently in filters without reducing surface area or restricting water flow. They can be used loose or placed inside the included mesh bag for easy installation and removal.
Suitable for freshwater and saltwater systems, Bio Balls are commonly used in koi ponds, water gardens, aquariums, aquaponics systems, fish hatcheries, and wastewater filtration setups. Available in 0.25, 1, and 2 cubic foot sizes to fit a wide range of filtration needs.
