The Fluval Foam Filter Block is used in the first stage of filtration process. The foam filter block captures large particles and debris, thus provides mechanical filtration which prevents particulate waste from prematurely clogging other filter media in the module stack.

The foam filter block is designed to prevent bypass, having a pore size that allows efficient water flow with less clogging for long-lasting filtration.

Benefits

Provides mechanical filtration

Removes the larger particles

Protects filtration equipment from damage due to clogging

Prevents premature clogging of other filter media

Enhances biological filtration

Suitable for freshwater and marine aquarium

Added Benefits: Biological Filtration

Although the primary purpose of Fluval Foam is mechanical filtration, biological activity will eventually occur within its pore structure.

Therefore, the Fluval Foam Block provides both mechanical and biological filtration benefits.
