AC Spiral Japan Filter Mat: Suitable for koi or garden pond

With the growing popularity of koi keeping and aquatic landscaping, water quality management has become a core aspect of maintenance.

AC Spiral Japan Filter Mat is designed specifically for pond filtration systems. Made from natural, eco-friendly materials, it contains no adhesive or fluorescent agents, ensuring a safe pond environment. Its unique spiral vine-like structure significantly increases the surface area, promoting the attachment of nitrifying bacteria to establish an efficient biofiltration bed while maintaining unobstructed water flow—effectively combining mechanical and biological filtration.

The enhanced 4cm high-density porous layer further improves impurity retention, is resistant to clogging, and is easy to cut and clean. Suitable for various pond filtration setups, it helps achieve clear and healthy water conditions.
