Here at Aqua One Store we only supply the latest spec Aqua One 102c Ceramic Cartridges as part of the 128c cartridge pack. . The porous ceramic balls remain the same, as does the plastic frame of the cartridge. What has changed is the material bonded to the front of the cartridge. This was a black polymer fibre material that blocked easily causing water flow issues. The latest version of the Aqua One 102c has been revised to include a much improved porous plastic mesh that is much more blockage resistant and should greatly improve water flow through the cartridge.

The Aqua One 1c Carbon Cartridge is supplied as half of the 128c filter cartridge pack. It is a disposable filter cartridge for use in the l Aqua One Aqua Nano set ups, the Betta Mono, Duo and Trio models and the Xpression Range of aquariums. .The 1c cartridge should be removed and discarded when blocked with fish waste and debris. This will usually be every four to six weeks. The Polymer ‘wool’ layer traps debris while the activated carbon removes odours and clarifies the water.
