How to Use
Rinse the Bio-Foam before first use if directed by the manufacturer. Place the foam in the designated media area of a compatible Fluval FX4, FX5, or FX6 canister filter according to the filter instructions.
During routine maintenance, rinse the foam in removed aquarium water to preserve more beneficial bacteria than rinsing under untreated tap water. Replace the foam when it becomes worn, damaged, misshapen, or difficult to clean.
Usage & Care Tips
- Use only with compatible Fluval FX4, FX5, and FX6 canister filters
- Rinse gently before first use if recommended on the package
- Clean during routine filter maintenance using removed aquarium water
- Avoid rinsing established foam under untreated tap water
- Do not replace all biological media at the same time
- Replace foam gradually when possible to reduce disruption to biological filtration
- Continue regular aquarium maintenance and water testing as needed
Important Biological Filtration Note
Bio-Foam can support beneficial bacteria, but it should not be the only part of an aquarium maintenance plan. Proper cycling, stocking levels, feeding amounts, water changes, and filter cleaning all affect aquarium water quality.
When replacing established filter media, avoid changing all biological media at once. Gradual replacement can help maintain a more stable biological filter.
