Pool filter sand can be purchased at larger home stores, or a gravel / sand yard, or water treatment stores, local pool suppliers, or online.
In graded sand filters the bed depth typically comprises m of – mm fine sand (effective size mm), m of – mm coarse sand, m of – mm fine gravel and m of – mm coarse gravel.
The ideal sand media for intermittent sand filters is a coarse sand with an effective size between mm and mm. The media sand grains should be relatively uniform in size having a low Uc value (less than ) to promote movement of water and prevent clogging.
