Overview

Enhance your aquarium maintenance with Fluval FX Carbon Foam pads. This 2-pack replacement media is designed for Fluval FX4, FX5 and FX6 canister filters, delivering a thoughtful blend of mechanical and chemical filtration. The pads work as a dual-function media, helping to keep water clear while addressing common tank odors and impurities with carbon-impregnated material.
