Sponge Filter for Fish Tanks, Medium Size

Biochemical Filtration

With an air pump as the power source, our biofilter combines mechanical and biological filtration to enhance water quality. Utilizing a multi-level filtration system, it ensures efficient purification. The sponge is designed to absorb fine particles, removing contaminants and maintaining a clean environment.

Controllable Water Flow

The water flow is controlled by the airflow, which is small and slow, ensuring gentle water movement without disturbing your fish.

Replaceable Filter Materials

Our filter includes two types of replaceable materials: - Sponge: Easily removable and replaceable, with a total of 4 sponges. - Ceramic Filter Balls: Two media boxes with ceramic filters, providing additional cleaning and eliminating bad substances.

Easy Setup

Connecting the filter is straightforward. Use a 4mm air hose to link the air pump to the tank filter. The outlet pipe in the sponge filter allows you to adjust the water flow direction and height (not including the pump and air hose; choose a powerful pump according to your tank size).

Multi-Layer Design

Featuring a multi-layer design with a large surface area, our filter ensures thorough filtration without any dead ends. The strong suction cup is securely anchored, and the base can rotate 360 degrees to adjust position.
