HQRP - 1.5 in Bio Balls Filter Media - 100 Pack Mesh Bag - Aquarium Pond Waterfall Fountain

These 1.5 in bio balls filter media help clarify water naturally by promoting gas exchange and increasing dissolved oxygen, supporting a healthier environment for aquatic life. Each spherical ball uses precise spine placement to pack tightly in many filter shapes without sacrificing surface area, creating more room for beneficial bacteria to colonize and assist in breaking down organic waste. Compatible with HOB filters / external filters / pressurized filters, they are designed for use in aquarium, pond, waterfall, and fountain setups with fresh or salt water, and can also be used in aquaponic applications and kio ponds. Made from high density polyethylene, this set includes 100 black bio balls (1.5 in / 3.5 cm diameter) and a black mesh bag with a plastic zipper (about 12 in x 9.5 in) so you can run the media contained or loose as needed; simply rinse and use.
