Aqua One BettaSense Carbon Filter Cartridge 2 Pack (322c / 25322c)
Keep your BettaSense aquarium water clean, clear, and healthy with genuine Aqua One BettaSense Carbon Cartridges — the genuine OEM replacement filter cartridge designed specifically for the Aqua One BettaSense aquarium filter.
Each cartridge combines mechanical and chemical filtration in one easy-to-replace unit — filter wool traps debris and particles mechanically, while activated carbon absorbs toxins, odours, discolouration, and harmful chemicals for crystal-clear water. The 2-pack keeps you stocked for your next two replacement cycles — ensuring you always have a spare on hand so you are never caught without one.
Regular cartridge replacement is one of the most important and easiest steps in betta aquarium maintenance. Replace every 4–6 weeks for optimal water quality and to protect your betta from harmful water conditions.
