Sicce's genuine Complete Cartridge for the Aqua Filtra 10 and Aqua Filtra 20 hang-on-back filters (Sicce code SVA0022), with two cartridges per pack. The Aqua Filtra 10 holds one cartridge and the Aqua Filtra 20 holds two.
Each is a ready-to-use cartridge with its frame and media already loaded, so you lift out the old one and slide in the new one. It filters in Sicce's three stages: a 20 ppi sponge for mechanical and biological filtration, activated carbon and zeolite for chemical filtration, and a fine wool pad for polishing. It does not fit the Aqua Filtra 40. For freshwater or saltwater tanks.
