Biological sponge filter for aquarium fish tank 103

The Biological Sponge Filter 103 is a compact and efficient filtration system designed for aquarium use. This cylindrical filter features a dense, black foam material that provides both mechanical and biological filtration. The sponge's porous structure creates an ideal surface for beneficial bacteria colonization while effectively trapping debris and waste particles. The filter includes a central tube with a sturdy base plate and top connector for easy installation and maintenance. Its design allows for gentle water flow, making it particularly suitable for tanks with small fish, fry, or shrimp. The filter can be easily connected to an air pump (not included) to create water circulation while performing its filtration duties. Regular cleaning is simple - just squeeze the sponge in aquarium water to remove trapped debris while preserving the beneficial bacterial colonies. This filter provides reliable, low-maintenance filtration for freshwater aquarium environments.
