If you’re trying to rid your pool of minute particles, then this is not the right type of sand to add to your filter. Silica sand only filters particles to a size of 20 microns or 0.0008 inches. Nicknamed industrial sand and quartz sand, silica sand is low-cost, widely available, and thus the most common. The granular silica naturally contains minerals, clay, coal, and quartz, with the latter more plentiful than the former ingredients. The last type of sand you might consider for your pool filter is good ole silica sand. The sand can keep your pool’s chlorine content balanced by attaching to chloramines. That’s not as microscopic as the particle size that a glass sand pool filter can capture, but it’s enough to grab the most common pool contaminants before they accumulate and cause a bigger issue later. When broken down into small sand-like particles for a pool filter, zeolite sand can catch particles that are at least 10 microns. Zeolite is a type of aluminosilicate microporous mineral that’s regularly used as a catalyst and adsorbent. The size of the particles that a glass and pool filter can capture is between three and five microns.Īlgae spores are often around this size, so by preventing them from lingering in the pool, you can prevent larger swathes of algae from growing in the water.
