Aqua One 5c Carbon Filter Cartridge – Triple Pack (three complete changes )

The Aqua One 5c Carbon and Polymer Wool Cartridge is a disposable filter cartridge pack for use in the Aqua One AquaStyle(AR) 980 aquarium. The C cartridges form the top layer of the trickle filter. Three packs of three cartridges are supplied ( Six large and three small for three full filter changes) and the cartridges should be removed and disgarded 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. An essential part of the Aqua One trickle-filter system . We’ve tried substitutes and we’ve tried othr filtration methods but nothing comes close the the original C cartridge from Aqua One.
