Fish Tank Filter Foam 50x50x4cm (19.7" × 19.7" × 1.6") – 30 PPI - Medium Coarse

This high-quality aquarium filter foam is perfectly suited for aquarium filtration systems, especially undergravel filter (UGF) setups.

• Dimensions: 50 x 50 x 4 cm

• Pore Size: 30 PPI (medium coarse)

The sponge’s structure provides an excellent surface area for beneficial bacteria to colonize, supporting a healthy and stable aquarium environment. The medium-coarse pores are designed to allow waste to pass through and settle at the bottom, while still offering effective mechanical and biological filtration.

Shrimp Mania Comment: “This is the exact sponge both I and KW Shrimps use in our UGF filters.”
