Green Matala Media

Medium Density

The Green Matala® filter media can follow thereby trapping a medium size particle. Both Green and Black mats clean out very easily by simply shaking the pieces out before draining the sump. When you use the Black or Green Matala® filter media for solids filtering you may use the garden hose to spray clean them. The dirt falls off very easily.

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.
