One full sheet equals 1.6 cubic feet, or 12 gallon volume.
Semi-rigid, self-supporting, and non-brittle.
Specific gravity: 0.95. Slightly buoyant.
Made of EVA material - Non-toxic to environment.
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 from 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 stands vertically and will not float. Matala stacked horizontally will hold each other down.
Due to its rigidity, the Matala can be wedged in place in the filter without support. It will hold its open 3-dimensional internal structure even if purposely crushed.
It is easy to cut. Use a hole saw to cut circles for pipe work. Use a jig saw with a fine tooth blade, or 8" long sharp carving knife, for free-form shapes. You can also use band saw, with a very fine tooth blade, or turn the blade and use the backside as knife.Use a masonry blade turned backwards on a circular saw.
When deciding how many sheets of Matala® are needed for your pond, think 1,2,3,4. This is the number of sheets per 1,000 gallons, depending on your fish load. The fish load really determines the volume of any media required. Many hobbyists' filters are too small for the fish load. Your Garden Pond could still function reasonably well because ponds are very resilient and manage to adjust to high fish loads even with small filters. However, a pond with a high fish load and a small filter will need to increase maintenance and care. You will likely have bigger algae problems and fish health issues if your filter is too small.
