FLUVAL Poly Foam Pad is designed exclusively for use with the Fluval C4 Power Filter hang-on filter. It delivers top performance by effectively carrying out the first two stages of mechanical aquarium filtration.

Thanks to its smart dual-sided design, it helps ensure that aquarium water remains crystal clear, transparent, and healthy for fish and other living organisms.

• Stage 1 (porous side): The outer porous side easily traps large dirt particles and organic debris.
• Stage 2 (dense polyester side): The inner, dense polyester side retains even the smallest suspended micro-particles, providing crystal-clear water.

• Compatibility: Fluval C4 Power Filter
• Material type: Sponge / Polyester (Poly/Foam)
• Filtration stages: Mechanical (Stage 1 & 2)
• Package contents: 3 pieces
