Aqua One Aquanano 30 Sponge 116S Cartridge Replacement Filter Sponge from B&Q

Aqua One

AquaNano 22 sponge foam replacement pack contains 1 biological filter sponge designed for Aqua One AquaNano range filters. It is easy to replace and helps maintain peak tank conditions and crystal-clear water. For best performance, we recommend using genuine Aqua One spare parts and replacing the sponge regularly, around every 8 to 16 weeks depending on use. To preserve beneficial bacteria, do not rinse the sponge under tap water, instead gently squeeze it out in a little aquarium water and discard the water afterwards. When the foam begins to collapse or becomes harder to rinse, it should be replaced.
