Filter sand is an extremely effective filter media because of its ability to hold back precipitates containing impurities. It forms a fine layer on top. *A grit size is defined by the distribution of grits retained on a sieve set up that meets the requirements of ANSI Table 2 or 3. For example, if the particle size of a material is described as -4 +40 mesh, then 90% or more of the material will pass through a 4-mesh sieve (particles smaller than 4.76 mm) and be retained by a 40-mesh sieve (particles larger than 0.420 mm).
