Instructions for use
Rinse the Polyester Filter Pads thoroughly before use and insert into the centre of the media cartridge, between two foam pads. To gain full benefit from the large surface contact area that the filter allows, remove the pad once it has captured the extremely fine particles, at the latest after 1 to 2 weeks. To ensure retention of the beneficial bacteria required for biological filtering, never change all filter media at the same time. Always add Cycle to the aquarium water after replacing the pad, to speed up the colonialization of beneficial bacteria.
