Matala is the first media which is actually made for the express purpose of filtering koi ponds. Made to handle the high solid waste levels associated with koi. Easy to clean. Acts as a substrate for biological filtering. Each pad has it’s own unique structure lending itself to a different job in filtration. The various densities can be used in sequence or separately for unique filtration requirements. Matala effectively separates large particles to small and still maintains a very aerobic and free flow of water without channeling. 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 sheets can be wedged in place in the filter without support.
Full sheets of Matala measure 48" x 39" x 1.5" thick.
When you use the Green Matala for mechanical / solids filtering, you may use the garden hose to spray them
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.clean.
