The Black Matala® filter media can be used as a support grate for other layers of media due to it’s very sturdy and open design. In a settling chamber the Black will slow down and trap very large particles and hair algae.
When you use the Black or Green Matala® filter mats for solids filtering you may use the garden hose to spray clean them. The dirt falls off very easily.
Full sheets must ship by truck. $$$$ Call for cost.
