If you live in area with drastic temperature changes, be sure to build your pond deep. Deeper ponds will have more stable water temperatures. The temperature in shallow ponds can fluctuate radically in spring. These fluctuations can make it difficult for beneficial bacteria to colonize.
The various densities can be used in sequence or separately for unique filtration requirements. This is one of the greatest characteristics which Matala has to offer. No other 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.
Matala is slightly buoyant and will not sink to the bottom of your filter. Matala stood vertically on end will not float. Matala stacked horizontally will hold each other down.
Due to it's rigidity the Matala can be wedged in place in the filter without support.
One sheet of Matala has the following characteristics:
Approximately 48" x 39" x 1.5" (120cm x 100cm x 4cm) for all densities; Black, Green, Blue and Gray.
Weight per sheet is between 6 to 8 pounds depending on density.
One sheet is 13 sq.ft.
8 sq.ft. equals 1 cubic ft of media.
One full sheet equals 1.6 cubic feet or 12 gallon volume.
Semi-rigid and self-supporting
Specific gravity: 0.95. Slightly buoyant.
Made of Thermopoly Propylene compound - Nontoxic to environment.
