This is a 6 pack of Fluval Polishing Pads (A244) for the Fluval 305 Aquarium Canister Filter System (A211) and the Fluval 405 Aquarium Canister Filter System (A216). These Fluval polishing foam pad filters are used as the Stage 2 filter media to clear cloudy water and reduce fine particles in the Fluval 305 and Fluval 405 Aquarium Filter Systems.
These Fluval water polishing pad replacements for the Fluval 305/Fluval 405 Aquarium Filter units are made of extra dense polyester foam to trap fine debris, particles, and impurities such as dirt, sediment, sand, rust, and more. Fluval polishing filter pads reduce the amount of particulate matter in your aquarium to help your aquatic pets thrive better.
Fluval 305/Fluval 405 polishing pad filter replacements should be changed approximately every 2-3 months, though they can be rinsed clean between filter changes to extend filter life.
This six pack of Fluval fine polishing pad replacement filters are known by Hagen part number A244. They can also be used with the Fluval 304 and Fluval 404 aquarium filter systems.
