Fluval Premium Betta Kit 20ltr replacement cartridge (4)
Genuine replacement media for the Fluval Premium Betta Kit 20 L. This four-pack of carbon-impregnated poly-carb cartridges restores mechanical and chemical filtration in the 20 L Betta Kit once the original media is exhausted.
Key features
- Carbon-impregnated polyester cartridge – traps debris mechanically while the carbon pulls dissolved impurities and odours from the water.
- Genuine fit – made for the Fluval Premium Betta Kit 20 L filtration chamber, no trimming needed.
- Four-pack – enough for roughly two to four months of scheduled changes.
Fits
Fluval Premium Betta Kit, 20 L (Fluval item FBK02) only. It does not fit the 10 L Betta Kit, which uses a different filter chamber.

Common questions
Does this fit the 10 L Betta Kit?
No – it's sized for the 20 L kit's filter chamber only.
How often should I replace it?
Roughly every 2–4 weeks, or sooner if flow drops noticeably.
Can I rinse and reuse a cartridge?
Rinsing extends a cartridge's mechanical life slightly, but the carbon component is single-use – once its odour and impurity removal is exhausted it won't recharge by rinsing.
