Matala is the first media which is actually made for the express purpose of filtering koi ponds.
Introducing R-Matala®, the perfect "drop in" media for Vortex filters and barrel filters.
R-Matala® has the same qualities as the sheets of Matala in a coiled pre-cut cartridge. Simply select the diameter roll and the density you need for your round tank and drop it in. R-Matala® will naturally wedge in place without any need for support.
