This is a 2 pack of Fluval Foam Block Pad Filters (A222) for the Fluval 205 Aquarium Canister Filter System (A206) and the Fluval 305 Aquarium Canister Filter System (A211). These Fluval foam pad filters are used as the Stage 1 filter media in the Fluval 205 and Fluval 305 Aquarium Filter Systems.
These Fluval foam pad replacements for the Fluval 205/Fluval 305 Aquarium Filter are made with porous foam to trap large particles, debris, and impurities such as dirt, sediment, sand, rust, hair, and more. Fluval foam filters reduce the amount of particulate matter in your aquarium to help your aquatic pets thrive better. They are especially suited for heavily populated aquariums.
Fluval 205 foam block filter replacements should be changed approximately every 2-3 months, though they can be rinsed clean between filter changes to extend filter life.
This two pack of Fluval foam pad replacement filters are also known by Hagen part number A222. Additionally, these filters will fit the Fluval 204 and Fluval 304 aquarium filter systems.
