Fluval Foam acts like a strainer to prevent waste from clogging biological and fine mechanical media that are used later in the Module Stack. Fluval Foam provides mechanical straining of particulate waste. It prevents particulate waste from prematurely clogging other filter media in the Module Stack. Although the primary purpose of Fluval Foam is mechanical filtration, biological activity will eventually occur within its pore structure. 2 pieces per pack
