The Gray Matala® will filter out a much smaller particle and yet still maintain good flow distribution. In larger systems all four types can be used in sequence to essentially remove all solids. The rounded or rolled media can be used in round tanks.
Matala works perfectly with upflow filter designs. 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.
R-Matala will naturally wedge in place without any need for support. Four sequential densities can be perfectly employed to achieve maximum solids / bio-filtration. Each roll is 6 inches thick with a tremendous potential to trap dirt and yet is super easy to clean. Simply drain the waste out your bottom drain and gently pour pond water over the R-Matala.Seven diameters are available: 22"; 24"; 27"; 30"; 37"; 42" and 48 inch.
