- Enhanced Oxygenation: Our Bio Balls are expertly designed to boost oxygen levels in your aquarium. As water flows through the filter balls, it breaks into smaller streams, maximizing the surface area exposed to air. This results in significantly higher dissolved oxygen levels, promoting a thriving aquatic environment. - Improved Filtration Efficiency: The unique porous structure of our bio media captures and breaks down small particles and debris, enhancing overall filtration efficiency. Combined with the improved water pathways they create, these bio balls ensure clearer, cleaner water for your aquarium. - Versatile Compatibility: Suitable for both freshwater and saltwater aquariums, our bio balls are easy to integrate into any filtration system. Simply place them in the filter chamber or biomedia compartment of canister filters, top filters, fish pond filters, or bottom filters. - Durable Construction: Made from high-quality, non-toxic materials, our bio balls are built to endure the constant flow and harsh conditions of aquarium environments. They maintain their effectiveness over time, providing reliable filtration support for years. - Convenient Size: Each bio ball measures 26mm in diameter, making them easy to clean and maintain. The package includes 200 bio balls divided into 4 media bags, ensuring you have plenty for your filtration needs. Use Scenarios: 1. Install in a canister filter to enhance water quality for a vibrant freshwater aquarium. 2. Add to a saltwater tank filter to support delicate marine life with optimal oxygenation. 3. Use in a fish pond filter to maintain clear water and a healthy ecosystem for your outdoor fish.
