Bioballs are a classic and highly effective biological filter media designed to cultivate beneficial nitrifying bacteria in your aquarium. This one-gallon container of high-density polypropylene balls provides a massive surface area for bacteria to colonize, efficiently breaking down toxic ammonia and nitrite into less harmful nitrate. In addition to their primary role in the nitrogen cycle, bioballs excel at promoting gas exchange, which helps increase dissolved oxygen levels throughout your system for healthier fish and invertebrates.

Each ball measures 1.5 inches in diameter and features a pegged surface, maximizing the available area for bacterial growth to an average of 22.7 square inches per ball. With approximately 80 bioballs per gallon, you get a significant amount of filtration capacity. This inert, non-leaching media is engineered to resist clogging with organic matter, ensuring consistent water flow and performance. Made in the USA, these bioballs are completely safe for use in both saltwater and freshwater aquariums.

This product is ideal for aquarists utilizing wet/dry filters, trickle filters, sumps, or custom gas exchange reactors who need a reliable and low-maintenance biological filtration solution. Their robust design and high efficiency make them a perfect choice for heavily stocked tanks or any system requiring enhanced nitrification and oxygenation. By providing a stable and extensive environment for beneficial bacteria, these bioballs help create a healthier and more stable aquatic environment.
