Matala Filter Media Rolls - Black - Low Density (R22BLK)

The Matala filter media rounds are 6" thick rolls, made for vortex filters, barrel filters and skimmers. With the same qualities as the Matala sheets, the Matala rounds are formed into coiled, pre-cut cartridges. they will naturally wedge into place without need for support. Although a loose fit will allow water and debris to flow around it. Do not cut or un-roll Matala coils. Using four sequential densities (black, green, blue, grey) can achieve maximum solids and biological filtration. Pads can be used in upflow filters as well -- simply invert the order, placing black at the bottom and grey at the top.

The Black Matala Rolls are used for filtering the largest of dirt particles. It can be used as a support grate for other layers of media due to its very sturdy and open design. In a settling chamber, Black Matala slows down and traps large particles and hair algae. They can also function as biological filtration with its high surface area.

These Matala Filter Media Rolls will fit into a 55 gallon drum.
