This kind of sand is called filter sand or silica sand, and it catches debris so that it doesn’t end up in the pool water.
What is #20 grade filter sand?
#20 Silica Sand is graded specifically to filter and trap particles in the range of 20 to 80 microns. Over time, dirt and debris that collect in your filter will cause your pressure gauge reading to increase. When it reaches 8 pounds above your clean filter reading, it’s time to perform a backwash.
Is Play Sand #20 silica sand?

Mason sand
Mason sand, sometimes called mortar sand, can normally be found at any sand/gravel yard or masonry supply yard. It is usually measured in yards.

What’s the difference between silica sand and regular sand?
Specifically, silica sand is made up of silicon dioxide (SiO2). In order to be considered a silica sand the material must contain at least 95% SiO2 and less than 0.6% iron oxide. If the sand does not meet this criteria, it will qualify as what’s often called ‘regular’ sand.
Is silica sand the same as beach sand?
Yes, most of our sands (and most sands sold in home improvement and big box stores) have crystalline silica in them because they contain quartz sand grains (which is the common name for crystalline silica).

Because crystalline silica is dangerous and can be harmful to both human and animal health, Pool/Filter Grade diatomaceous earth should only ever be used for filtration. A majority of Food Chemical Codex Grade (Food Grade) DE products, on the other hand, are uncalcined and are largely composed of amorphous silica.
How do you find the bottom grade of a swimming pool?
All dimensions are from the top of the panel and not top of coping. Find the finished pool bottom grade by using a plumb bob at all string intersection points in the deep end. Drive pins into each corner of the hopper at the point of which the plumb bob lands. Attach string lines to the pins at the properly finished grade.
What is poolpool grade diatomaceous earth?
Pool Grade diatomaceous earth is calcined, meaning it has been heat-treated and activated for use in filters. The high temperatures further harden the diatom exoskeletons, creating a better filtering agent. This process also turns the silicon dioxide within the DE into crystalline silica.
