1.Enhanced Oxygenation: The shape and design of our Bio Balls work wonders in increasing the oxygen content of the water. As water flows through the filter balls, it breaks up into smaller streams and eddies, which significantly expand the surface area of ​​the water exposed to air. This results in a massive increase in dissolved oxygen levels. A welloxygenated aquarium is a happy, y aquarium 2.Improved Filtration Efficiency: Aquarium bio media increase overall filtration efficiency. The porous nature of the bio media helps capture and break down small particles and debris in the water. This, combined with the expanded water pathways they create in the filtration system, allows for a more thorough filtration process, resulting in clearer, cleaner water for your aquarium 3.Flexible and : Aquarium bio balls are suitable for all types of aquariums, whether you have a freshwater or saltwater setup.
