Sieve Analysis Test of Sand is done to check the gradation of sand particles. Sand particle distribution in sand volume is important for good quality concrete and mortar. In this test, the sand sample is passed through a series of IS sieve sizes ordered from bigger to a smaller size at the bottom.
All sand is different, so don't trust just any old bag of sand. Silica is definitely the way to go. If you get number 20 silica sand, that means it will filter up to 20 micron particles (much much smaller than the human eye can see). The downfall is silica will get some algae but not prevent algae outbreaks. Some algae an be 5-10 microns in size.

Any beads that pass through are captured and measured.
Essentially, the Grit Size is determined by how much grit passes through or is retained at certain sieve sizes. The Certified or Inspection Test Sieves each have a number corresponding to a size in the United States Standard Sieve Series (aka USS), with screen openings specified by the American Society for Testing and Materials ASTM E-11 table .
Media with small grain size slow the water movement and increase the chance of clogging. The effective size (D 10) and uniformity coefficient (Uc) are the principal characteristics of granular media treatment systems. The ideal sand media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm.
