Fluval 4Plus Polyester Filter Pads have been specially developed as a fine filter medium for the Fluval 4Plus Underwater Filter.
It is ideally suited to filtering out extremely fine suspended particles and contaminants.
Rinse the Polyester Filter Pads thoroughly before using and place into the center of the media cartridge.
To gain full benefit from the large surface contact area that the filter allows, remove the pad as soon as it has captured the extremely fine particles, or after 1-2 weeks.
