Fluval AC50 Filter Media Maintenance Kit
The Fluval AquaClear AC50 Filter Media Kit is a value pack that refreshes every stage of media in your AquaClear 50 (AC50) power filter at once. It bundles mechanical, chemical, and biological media in a single box, so you get a full filter service for less than buying each insert on its own. Works in both freshwater and saltwater aquariums.
Need to top up just one type of media? Grab an individual BioFoam, Activated Carbon, or BioMax insert, or browse the full Filter Media & Cartridges collection.
What's Inside
| Media | Qty | Job |
|---|---|---|
| BioFoam | 1 | Mechanical + biological: traps waste and debris and hosts bacteria |
| Activated Carbon | 2 | Chemical: removes odors, toxins, and discoloration |
| BioMax | 1 | Biological: porous rings that promote beneficial bacteria |
Features
- Complete media refresh for the AquaClear 50 in one box
- Covers all three stages of filtration: mechanical, chemical, and biological
- Value pack priced lower than buying the inserts separately
- Each insert is pre-cut to fit the AquaClear 50 media basket
- Works in freshwater and saltwater aquariums
How to Use
Stack the media in the AquaClear basket from the bottom up: BioFoam first, then the activated carbon, then BioMax on top. Rinse the foam and BioMax in used aquarium water at each cleaning and reuse them; replace the carbon about every three to four weeks. To protect your biological filter, avoid changing every piece of media at the same time. Stagger the carbon changes and keep at least some established BioFoam or BioMax in place.
