Aquatic Experts - 1" Bio Balls Filter Media for Aquarium and Pond, 200 Count with 4 Mesh Bag

Our bio balls for aquarium filter media feature spines to increase their surface area and provide enough space for many beneficial bacteria to colonize. These good bacteria help break down harmful organic waste. The spherical shape and precise spine placement of the bio balls' pond filters allow them to pack tightly into any shape or filter type without compromising the surface area. Made from high-density plastic, these pond bio balls for fish tank are lightweight yet robust enough to keep their shape for long. They are 100% polypropylene making them reliable biological filtration media for fresh and saltwater. When organic waste accumulates in the bio balls for fish tank, gently rinse them with dechlorinated water to remove dirt and refresh the bio balls. Use our FilterFirst, dual-density bonded filter pad, or water polishing pad to capture large particles before they can be trapped in the bio balls. We deliver approximately 200 1-inch bio balls with 4 mesh bags. Use them in koi ponds, saltwater aquariums, freshwater fish tanks, aquaponics, fish hatcheries, and more.
