Fine particles can remain in aquarium water after coarser media has done its job. These pads provide a finer filtration stage for aquarium owners maintaining a canister filter, with the aim of supporting clearer water and ongoing filter performance. Their format is designed for the Fluval FX series models named below, so matching the filter model and pad size is an important part of choosing the right replacement.
