Medium Density Green Matala Filter Media
Introducing Matala®, the advanced filter media for today's serious pond enthusiast. One look at Matala® will convince you of its practical and versatile qualities. The open, highly aerobic 3 dimensional structure promotes healthy water conditions and ease of cleaning in most non-pressurized filter designs. Matala® is a filter media that is simple and that works.
Matala effectively separates large particles to small and still maintains a very aerobic and free flow of water without channelling. Matala is slightly buoyant and will not sink to the bottom of your filter. Matala stood vertically on end will not float. Matala stacked horizontally will hold each other down. Due to it's rigidity the Matala can be wedged in place in the filter without support.
Great for trapping medium sized partiles and biofiltration. A good biofilter needs a lot of surface area with open spaces between for good aerated water flow. A high surface area is useless if the passageways are so small that water flow cannot penetrate.
