How to Use
Install the foam blocks in the compatible Fluval canister filter according to the manufacturer’s instructions. Make sure the foam is seated correctly before restarting the filter.
Mechanical foam helps collect larger debris before water passes through other filter media. Using mechanical filtration before biological media can help reduce debris buildup in the rest of the filter.
Maintenance Tips
- Rinse foam before first use if recommended on the package
- Rinse during regular filter maintenance using removed aquarium water
- Avoid rinsing established filter media under untreated tap water
- Replace foam when it becomes worn, misshapen, or difficult to clean
- Do not replace all biological media at the same time
- Check filter flow regularly and service the filter when output slows
- Adjust maintenance frequency based on stocking level, feeding, and bioload
Important Filter Media Note
Fluval Foam Filter Blocks are primarily mechanical filter media. They help trap debris, but they do not replace biological media, chemical media, water changes, proper stocking, or routine aquarium testing.
For best filter support, use mechanical foam along with appropriate biological media and any chemical media needed for the aquarium setup.
Frequently Asked Questions
What filters does the Fluval Foam Filter Block fit?
This foam filter block is designed for Fluval 206, 207, 306, and 307 external canister filters.
What type of filtration does this foam provide?
The Fluval Foam Filter Block provides mechanical filtration by helping trap debris, particles, uneaten food, and waste.
How often should I replace the foam?
Replacement timing depends on aquarium conditions and media wear. The foam can be rinsed and reused, then replaced when it becomes worn, loses structure, or no longer rinses clean.
Can I rinse this foam under tap water?

Yes, it can be used in compatible freshwater, marine, and FOWLR aquariums when installed and maintained according to the manufacturer’s instructions.
Does this replace biological media?
No. This foam block is primarily used for mechanical filtration. Biological media should still be used as part of a complete canister filter setup.
