Fluval Bio-FX 5 L

BIO - FX is a top - notch biological filter media suitable for canister filters and sumps of all sizes, even Fluval's renowned FX series. Its unique design features a deep pore structure filled with interconnected micro - tunnels. This creates an incredibly large surface area where billions of beneficial nitrifying bacteria can grow and flourish. Made from a safe and inert ceramic material, it ensures long - lasting and reliable performance. The linked cavities in BIO - FX allow for smooth and even water flow, preventing blockages and enabling better contact time for highly effective biological filtration. By promoting the growth of a high concentration of nitrifying bacteria, it rapidly and efficiently reduces ammonia and nitrite levels, leading to a healthier aquarium environment. For best results, rinse it monthly with aquarium water and replace part of it every 6 months. Place it in the last stage of the filtration process for optimal filtration. In most aquariums, one layer of BIO - FX in the filter basket is enough, but for aquariums with higher bio - loads, you can use additional BIO - FX.

Using BIO - FX is easy. For most aquariums, just add one layer of it to the filter basket. If your aquarium has a high bio - load, you can add more. It's best to place it in the last stage of the filtration process. To keep it working well, rinse it with aquarium water once a month. Every 6 months, replace part of the media. This will help maintain a healthy environment in your aquarium by reducing ammonia and nitrite quickly and efficiently.
