The set includes 300 black bio balls, each about 1.02 inches in diameter, plus five black mesh filter bags with a zipper for quick, secure material handling. The compact spheres are uniform in size and finish, offering a clean, professional look in your filter chamber.\u003c\/p\u003e\n  \u003cp\u003eThese spheres are molded from durable plastic and feature a biochemical cotton layer inside. The combination provides a multi-layer media option that can be used in canister filters, pond filters, or inside tanks to help support beneficial bacteria and keep systems running smoothly. The black color helps the media blend into most tanks, reducing visual disruption while maintaining filtration effectiveness.\u003c\/p\u003e\n  \u003ch3\u003eQuality and design highlights\u003c\/h3\u003e\n  \u003cp\u003eThe biomedial design pairs sturdy plastic with an inner cotton filter layer.
