The Fluval Edge pre-filter foam is designed as the first filtration layer for Fluval Edge aquariums. By placing the foam over the filter intake, large debris particles are captured immediately before they reach the main filter. This keeps your filter clean for longer and makes it operate more efficiently.

In addition, this foam provides extra protection for small fish, shrimp, and young animals. They will no longer be sucked into the filter, preventing injury or death.

The open structure of the foam ensures good water flow without hindering filtration. At the same time, the foam helps to soften the flow in the aquarium, which is especially important for sensitive fish.

By removing debris at the intake, the load on the biological filter media is reduced. This results in more stable water parameters and less maintenance.

Installation is easy: slide the foam over the intake pipe and it is immediately ready for use.
