It's designed to be used in both biological and mechanical filters and comes in varying densities to suit your needs. It's very lightweight, it's easy to cut and use in conjunction with other densities of media. It's designed to trap particulates and debris and provides a huge surface for beneficial bacteria to populate.
Rhe 6" thick rolls are the perfect size to capture particulate matter are super easy to clean.
Round Matala come in 11 sizes 17", 18", 22", 24", 27", 30", 32", 33", 37", 42" and 48 inch.

Low Density BLACK Matala Filter Media
Due to it's strong sturdy design, it's great as a support for all other media densities. Great for use in a pond filter settling chamber where the it can slow down and trap algae and large particulate matter. You can use a hose to wash off Green or Black filter media, the dirt and muck will fall right off.
Medium Density GREEN Matala Filter Media
The Green Filter Media traps a medium size particle. Really easy to clean, just shake out the pieces before draining the filters sump. Use a garden hose to wash clean.
High Density BLUE Matala Filter Media
The Blue filter media will filter out a smaller particulates and maintain an excellent flow. In larger pond filter systems all four types can be used in sequence to essentially remove all solids.
Super High Density GREY Matala Filter Media
Grey Filter media will filter the smallest particles and maintain flow
The best situation for Matala Filter Media is if it is standing up in a vertical position rather than laying flat. It allows for better flow, and is a bit easier to clean. Try to stagger the Filter media vertically with varied filter media densities to achieve the most optimal removal of particles. Try using a Green next to a Grey which will give good flow around the Grey media yet trap solids in the Green one.
