Fluval Betta Aquarium 22.7L Poly Carb Cartridge (4)

This Fluval Betta Poly/Carbon Cartridge – 4 Pack is the official replacement media designed exclusively for the Fluval Betta Premium Aquarium (22.7L). Each cartridge combines mechanical and chemical filtration, ensuring your betta tank stays clean, clear, and stable with minimal effort.

The outer poly fibre layer captures fine particles such as waste, excess food, and plant debris, helping keep the water visually clear. Inside, the activated carbon core works continuously to remove odours, dissolved impurities, and discolouration, leaving the aquarium fresh and free of unwanted contaminants.

These cartridges are made to fit perfectly within the Fluval Betta filtration module, maintaining the gentle flow rate required to keep long-finned bettas comfortable. Installation is straightforward—simply slide the old cartridge out and insert a new one. For optimal performance, Fluval recommends replacing the cartridge every 2 to 4 weeks, depending on feeding and maintenance practices.

This 4-pack provides several months of filtration support, making it a convenient choice for ongoing aquarium care.
