KSY Aquatics Aquarium Sponge Filter, Air-Driven Bio Filter for Shrimp, Fry and Small Fish

Gentle Filtration for Everyday Aquarium Care

This air-driven sponge filter provides gentle water movement while helping trap suspended particles and support biological filtration. It is well suited for shrimp, fry, bettas, small fish, breeding tanks, and other aquarium setups where softer flow is preferred.

Mechanical and Biological Filtration

Water passes through the porous sponge, helping capture floating debris while providing surface area for beneficial bacteria to colonize. This combines mechanical and biological filtration in one simple reusable filter.

Three Sizes for Different Aquarium Setups

Choose from Small, Medium, or Large depending on your available tank space and filtration needs. Each size includes a 7 cm uplift tube and a 2.3 cm outer-diameter top connection.

Simple Setup and Easy Maintenance

The filter can be connected to an air pump, compatible pump intake, top filter, or external filter setup depending on your equipment. Before first use, soak the sponge in aquarium water and gently squeeze it underwater to release trapped air. For routine cleaning, rinse the sponge in removed aquarium water rather than tap or hot water.
