Matala Filter Media Rolls - Grey - Super High Density (R22GRY)

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 Grey Matala filters out the smallest particles, while still maintaining good flow distribution. It should be used as a final stage in the filter flow and as a high efficiency biological filter media. Nitrifying bacteria thrive on the Grey Matala.

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