SunSun Filter Sponge Blue for HW-304A, HW-304B, HW-404A & HW-404B (2 Pack)

The SunSun Blue Filter Sponge is an original replacement mechanical filter media designed for SunSun HW-304A, HW-304B, HW-404A, and HW-404B external canister filters. Its carefully selected foam density efficiently captures suspended particles, waste, and fine debris, helping to maintain crystal-clear aquarium water.

In addition to mechanical filtration, the sponge provides a large surface area for beneficial nitrifying bacteria to colonise. These bacteria are essential for biological filtration, helping to maintain a stable, healthy aquatic environment for fish and aquatic plants.

Supplied as a pack of two, these washable and reusable replacement sponges are ideal for routine maintenance, ensuring your SunSun canister filter continues to operate at maximum efficiency.
