The various densities of Matala filter media can be used in sequence or separately for unique biological filtration requirements. This is one of the greatest characteristics which Matala has to offer. No other bio-filter media on the market can perform this step-wise filtration. Matala effectively separates large particles to small and still maintains a very aerobic and free flow of water without channeling. Easy to cut to size these filters will last 3-4 times as long as conventional filter materials.
