Japanese Matting is a firm favourite amongst koi keepers as it provides a great level of biological filtration and can be cut into any shape for the perfect fit. The thick textured matting provides a great place for biological bacteria to thrive and breakdown the nitrites and ammonia in the water.
It can be used as a thick sheet or cut into cartridge shapes to fit into a variety of pond filters. This means the perfect fit every time and a thorough clean.
The sheets measure 1.2m x 1m.
