How to Use
Install the Bio-Foam blocks in the compatible Fluval 406 or 407 canister filter according to the manufacturer’s instructions. Make sure the foam is seated properly before restarting the filter.
During maintenance, rinse established Bio-Foam in removed aquarium water rather than untreated tap water. This helps preserve more beneficial bacteria than rinsing under chlorinated water.
Maintenance Tips
- Use only with compatible Fluval 406 and 407 canister filters
- Rinse before first use if recommended on the package
- Rinse during maintenance using removed aquarium water
- Avoid replacing all biological media at the same time
- Replace foam when it becomes worn, damaged, misshapen, or difficult to clean
- Check filter flow regularly and service the filter when output slows
- Adjust maintenance frequency based on stocking level, feeding, and bioload
Important Biological Filtration Note
Bio-Foam can support beneficial bacteria, but it does not replace proper aquarium cycling, regular water changes, correct stocking levels, or routine water testing. When replacing established filter media, avoid changing all biological media at once when possible.
Frequently Asked Questions
What filters does Fluval Bio-Foam 406/407 fit?
This Bio-Foam is made for Fluval 406 and Fluval 407 External Canister Filters.
Is Fluval Bio-Foam mechanical or biological media?
It functions as both mechanical and biological filter media. The foam helps trap debris and provides surface area for beneficial bacteria.
How often should Bio-Foam be replaced?
Replacement timing depends on aquarium conditions and media wear. Rinse and reuse the foam during maintenance, then replace it when it becomes worn, damaged, or starts to break down.
Can I rinse Bio-Foam under tap water?
It is better to rinse established Bio-Foam in removed aquarium water. Untreated tap water may contain chlorine or chloramine, which can affect beneficial bacteria.
