Fluval U4 Filter Foam Pad (2pk)

The Fluval U4 Foam Pad (2pk) provides essential mechanical filtration for the Fluval U4 Internal Filter, capturing large debris and solid waste particles before they reach finer filter media. This ensures clear water, improved flow, and longer filter life.

Crafted from durable, high-quality foam, these pads are designed to maintain their shape and porosity over time, allowing for effective debris trapping without restricting water movement. By removing uneaten food, fish waste, and plant matter, they create a cleaner, healthier environment for aquarium fish and plants.

The Fluval U4 Foam Pad is easy to install and replace — simply insert it into the filter cartridge compartment. For best performance, rinse the pad in aquarium water during routine maintenance and replace it every few weeks or when heavily soiled.

Suitable for both freshwater and marine aquariums, these foam pads form the first stage of Fluval’s multi-stage filtration system, working in combination with biological and chemical media to deliver crystal-clear results.
