Rigid and extremely durable. Versatile filter media is perfect for use in biological filters, settling tanks, and pump pre-filters. Simply cut Matala to size with a standard serrated kitchen knife to accommodate use in existing filter. Offered in four densities: BLACK (super-coarse), GREEN (coarse), BLUE (fine) and GREY (super-fine).

Offered in four densities: 

BLACK (super-coarse)

The Black Matala can be used as a support grate for other layers of media due to its very sturdy and open design. The Black Matala is used widely as a large particle size solids filter. A single layer 1.5 inch thick can filter out things like leaves, large clumps of algae, cigarette butts, seed pods, etc. However, if you use multiple layers it can really filter out some smaller particles like medium size koi pellets, small bits of algae, tiny leaves and plant debris, etc.

The Black Matala is actually the most used density for waste water treatment / sewage systems. It is currently being used in municipal waste water treatment plants in various cities around the world. The open flow configuration allows high volumes of dirty water with very high biological oxygen demand to pass through without clogging. The bacteria growing on these strands form thick biofilms in an oxygenated environment with even flow distribution.

GREEN (coarse)

The Green Matala is best used after the black when used in line with the other media thereby trapping the medium size particles. Both Green and Black clean out very easily by simply shaking the pieces out before draining the sump.

A good biofilter needs a lot of surface area with open spaces between for good aerated water flow. A high surface area is useless if the passageways are so small that water flow cannot penetrate.

BLUE (fine) 

The Blue Matala® filter media will filter out a much smaller particle and yet still maintain good flow distribution. In larger systems all four types of matala media can be used in sequence to essentially remove all solids.

Matala filter media is a progressive filter Material that is self supporting and multifunctional. Used for prefiltering, mechanical filter media, biological filtration, spawning mat, plant protection, and as a support for other filter medias. Uniquely versatile, Matala filter mats are easy to work with and can fit most all filtration needs.

GREY (super-fine) 

The Grey Matala® Filter mats will filter out a much smaller particle than the Black, Green, or Blue, and yet still maintain good flow distribution. In larger systems all four types can be used in sequence to essentially remove all solids.

Matala media works perfectly with upflow filter designs. The ideal configuration would be the Matala® filter media stood vertically rather than flat. This allows for easier cleaning. All you do is grab an individual piece and shake it up and down to clean it. If your filter chamber is packed to tight, take out one piece first.

Laid flat you will have to remove all the pieces to get to the bottom dirty piece. Stagger your vertical pieces with different Matala mat densities to achieve better solids removal or better biological filtering depending on the tank capacity. A Green piece next to a Grey piece for example will give good flow around the Grey one and trap solids in the Green one
