Fluval Foam Insert

Fluval Foam (4 plus 4-pack) provides mechanical straining of particulate waste. It prevents particulate waste from prematurely clogging other filter media in the module stack.

• Durable foam filters
• Traps particles and debris
• Prevents waste from clogging other filter media

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