Coralife Bio Balls Biological Filter Media

Coralife Bioballs have an advantage over traditional biological media, in that they were designed to maximize biological filtration in less space, to achieve a healthier aquarium environment in either fresh or saltwater marine aquariums.

One gallon of bioballs is approximately 225 bioballs, and has a surface area of about 21.5 square feet due to their spherical nature, allowing air pockets and surface areas to benefit from the most efficient amounts of oxygen and water to flourish. This increased surface area supports between 45 and 60 gallons of marine life.
