Fluval AquaClear AC70 Bio-Foam 3-Pack – AC70 Filter Media

Fluval AquaClear AC70 Bio-Foam 3-Pack includes replacement foam inserts made for the Fluval AquaClear 70 Power Filter. These foam inserts provide mechanical filtration by helping trap debris and also provide surface area where beneficial bacteria can grow.

Bio-Foam can be rinsed and reused during routine maintenance until the foam becomes worn or begins to break down. It is useful for freshwater and saltwater aquariums using the AquaClear 70 filter, including community tanks, planted aquariums, cichlid tanks, and other appropriately sized setups.

How to Use

Install the Bio-Foam insert in the AquaClear 70 filter basket according to the manufacturer’s instructions. Make sure the foam is seated properly before restarting the filter.

During maintenance, rinse established 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 the Fluval AquaClear 70 Power Filter
• 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.
