count Large Bio Balls for Pond Filter, Aquarium Filter, and Outdoor Ponds with Mesh Bag

These large bio balls are covered in spines, increasing their surface area to nearly 2 square feet, providing ample space for beneficial bacteria to colonize. Receiving approximately 300 1.5″ bioballs in a 14″x20″ mesh bag, these units can be used loose or in the mesh bag with a plastic zipper.

Their spherical shape and precise spine placement allow them to pack tightly into any filter type without losing surface area, making them suitable for various applications. Made from high-density plastic, these bio media balls are lightweight yet tough, ensuring they maintain their shape and never degrade or wear out.

These biofilter balls are made from 100% polypropylene, making them a safe and reliable biological media for use in koi pond filters, freshwater aquariums, and saltwater fish tanks. They can be used in aquaponics systems, as well as other applications.

One of the main advantages of these bio balls is their ability to withstand debris passage, unlike porous lava rock. While lava rock’s tiny pores make it prone to clogging, our bio balls’ unique spines allow debris to pass through, keeping their surface area intact.

Furthermore, these bio balls do not contain a sponge center, unlike other bio ball filter media. This means that they won’t trap gunk, ensuring good water quality. With their solid center and spines, these bio balls can withstand even the toughest water conditions.

Manufactured in the USA, these bio balls offer superior penetration for beneficial bacteria growth and are an excellent choice for anyone looking for high-quality, reliable, and easy-to-maintain filter media.
