Sand Pool Filters. The sand used in a pool filter is #20 silica sand that's approximately 45 to 55 millimeters in size. Sand filters only filter down to the 20- to 100-micron range, meaning you'll be able to see some of the impurities in your swimming pool water. To put it in perspective, algae is approximately 1.5 to 15 microns.

When these minerals form in the presence of sand, they act like glue, binding the sand particles together. In lab tests, the process worked with all types of sands, from common silica and calcareous sands to iron sands, which are often found near volcanoes. "After being treated, the sand looks like a rock," Rotta Loria said.
