CNZ® Bulk 1-inch 25mm Bioballs (4000 cnt) Bio Filter Media

Description

Optimize biological filtration in your aquarium system. Versatile, space-saving bio-balls efficiently process more harmful organic materials. The secret is their unique, geometric design that dramatically increases surface area to cultivate more beneficial bacteria. One gallon of bio-balls has a surface area of approximately 21-1/2 square feet. Safely maintain larger biological loads even in aquariums with relatively smaller filter areas. Place in wet/dry filters to improve biological filtration. Each bio-ball measures approximately 1 inch. Use one gallon per 45 to 60 gallons of water.
