Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it ...

(8327 L) Sand Filter from Bestway® is a highly efficient and environmentally friendly way to keep clean water flowing through your above ground pool. It is a more cost effective solution as the pump uses silica sand instead of a traditional filter cartridge. While those cartridges need to be replaced every 2 weeks, silica sand lasts up to 3 years.
