## Overview

The Hagen Fluval 306/406 Bio-Foam is a dual-action filtration upgrade designed to enhance both mechanical and biological filtration in Fluval canister filters. Its porous design maximizes surface area for beneficial nitrifying bacteria, while effectively capturing fine particles missed by initial foam layers. Compatible with freshwater and marine tanks, it includes two bio-foam pieces tailored for Fluval 306/406 models, ensuring superior water clarity and healthier aquatic environments.

Fluval bio-foam combines mechanical and biological filtration. Its porous structure increases surface area for the growth of helpful nitrifying bacteria. In addition, it traps small particles that are not retained by the first stage of foam filtration. The numerous grooves in the bio-foam maximize the surface area for beneficial bacterial colonization. The fluval 306/406 bio-foam includes 2 smaller bio-foam pieces to fit within the compartments of the bottom basket of fluval canister filters 304, 305, 306, 404, 405, and 406.
