Hagen Fluval 306/406 Bio-Foam

Description

🧼 Elevate your aquarium’s clean game—because your fish deserve the best!

The Hagen Fluval 306/406 Bio-Foam is a dual-purpose filtration upgrade designed to enhance both biological and mechanical filtration in Fluval canister filters (models 304-406). Its porous structure increases surface area for beneficial nitrifying bacteria, while its fine foam traps small particles missed by initial filtration stages. Suitable for freshwater and marine tanks, it includes two bio-foam pieces that fit seamlessly into the filter’s bottom basket, ensuring superior water clarity and healthier aquatic environments.
