Fluval AC20 Bio-Foam - 3 pack

The new Bio-Foam in the AC series has been redesigned to enhance its ability to trap fine particles. The foam structure is more refined, providing better mechanical filtration while maintaining optimal water flow. This ensures that more debris is captured before water moves to the chemical and biological stages. The new Bio-Foam blocks offer a greater surface area for beneficial bacterial growth compared to the older versions. This improvement increases the biological filtration capacity, supporting a healthier and more stable aquarium environment. The Bio-Foam in the AC series has been adjusted to fit more securely within the media basket, minimizing the chances of water bypass and ensuring that all water passes through the foam. Additionally, the material used is more durable, extending the life of the foam and reducing the frequency of replacement. The new Bio-Foam is designed to work seamlessly with the other updated media options in the AC series, such as the new versions of Activated Carbon and BioMax. This ensures a more integrated and effective filtration system across all stages. These upgrades reflect Fluval’s commitment to improving the overall performance and user experience of their products, making the new Bio-Foam more effective than its predecessors. Ideal for aquariums between 5 - 20 US gallons (18 - 76 L). 3 pack.
