Fluval Betta Aquarium 22.7L Poly Carb Cartridge (4)

The Fluval Betta Aquarium Poly/Carbon Cartridge (4 Pack) is the official replacement media for the Fluval Betta Premium Aquarium Kit – 22.7L. These cartridges combine mechanical and chemical filtration to keep betta aquariums clean, clear, and healthy with minimal effort. Each cartridge contains a poly fibre layer that traps fine debris such as uneaten food, fish waste, and plant particles. Inside, the activated carbon core works to remove odours, discolouration, and impurities, leaving water sparkling and improving overall tank clarity. Designed specifically for Fluval’s gentle-flow Betta filtration system, these cartridges maintain the low-current environment needed to keep bettas comfortable without compromising water quality. They are simple to install and replace, making them ideal for both beginners and experienced aquarium keepers. To ensure peak filtration performance, Fluval recommends replacing each cartridge every 2–4 weeks, depending on aquarium load and maintenance routine. This 4-pack provides convenient coverage for multiple maintenance cycles, helping maintain a consistently stable environment for your betta. 1.
