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.
