Fluval FX5 Filter Foam is designed for efficient mechanical filtration, capturing debris and solid waste before it reaches finer filter media. Each foam insert is shaped to fit perfectly within the FX5 media baskets, helping to prevent water by-pass and maximise filtration effectiveness. The foam’s optimised pore structure supports strong water flow while resisting clogging, making it a reliable first stage in both freshwater and marine aquarium setups.
