Why Replace Your Carbon Cartridge?
Activated carbon doesn’t last forever.
Over time it becomes exhausted and gradually loses its ability to remove impurities from your aquarium water.
Replacing your cartridge every 6–8 weeks helps:
✔ Remove unpleasant odours
✔ Reduce yellow water and discolouration
✔ Remove residual medications after treatment
✔ Improve water clarity
✔ Maintain effective filtration
✔ Keep your aquarium looking its best
Genuine Aqua One Quality
Using genuine Aqua One replacement cartridges ensures the correct fit and optimal performance for your aquarium filter.
Unlike some aftermarket alternatives, genuine cartridges are designed specifically for your Aqua One filter, helping maintain proper water flow and filtration efficiency.
Aquarium Spare Parts Expert Tip
? Rinse your new cartridge before installation.
Before placing the cartridge into your filter, give it a quick rinse under clean tap water for around 20–30 seconds. This helps remove any loose carbon dust and prevents temporary black particles from entering your aquarium after installation.
Replacement Schedule
For the best filtration performance we recommend:
- Carbon Cartridge: Replace every 6–8 weeks
- Filter Wool: Replace every 2–4 weeks (where fitted)
- Biological Media: Rinse in aquarium water only and replace only when required
Regular maintenance helps keep your filter operating efficiently while providing the healthiest possible environment for your fish.
Frequently Asked Questions
Can I rinse and reuse the carbon cartridge?
No. While you can gently rinse debris from the outside, activated carbon becomes exhausted over time and should be replaced rather than reused.
Does this cartridge remove ammonia?
No. The activated carbon is designed to remove dissolved organic compounds, odours and medication residues. Biological filter media is responsible for processing ammonia and nitrite.
Can I use this after treating my fish with medication?
Yes. In fact, this is one of the most common reasons to replace your carbon cartridge. Installing fresh activated carbon after completing a medication treatment helps remove any remaining medication from the water.
How do I know when it’s time to replace the cartridge?
As a general guide, replace the cartridge every 6–8 weeks, or sooner if water flow is reduced or the carbon has been heavily used after medication or water quality issues.
