Matala Filter Media Rolls - Blue - High Density (R22BLU)

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 Blue Matala is used for filtering smaller particles, while still maintaining good flow distribution. It is a superb biological filter media, due to its high available surface area and open passageways that allow nitrifying bacteria to thrive. Blue Matala is commonly used where one pad is desired.

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