 Rolled Matala Cartridges for Round Filter Tanks
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.
NO CUTTING, NO WASTE, NO HASSLE!
 Four sequential densities can be perfectly employed to achieve maximum solids / biofiltration.
Each roll is 6 inches thick with a tremendous potential to trap dirt and yet is super easy to clean. Simply drain the waste out your bottom drain and gently pour pond water over the R-Matala®.
The open structure of the media provides excellent flow-through without channeling. Since most round tanks are also rather tall you can stratify the R-Matala® in sequential layers to make best use of the chamber.
NO DEAD ZONES, NO CHANNELING!
Seven diameters are available: 22"; 24"; 27"; 30"; 37"; 42" and 48 inch.
Other diameters are available upon special request
