Designed specifically for the smaller Fluval FX2 performance canister filters, Bio-Foam captures large particles and debris for effective mechanical filtration. While the FX2 Bio-Foam is thinner than traditional Bio-Foam, its rippled pattern offers more surface area to effectively trap large debris and increase biological activity, enhancing the biological filtration process. Custom fit to prevent debris bypass Ideal pore size allows efficient water flow and longer media lifespan Rippled pattern offers more surface area to effectively trap large debris
