Silica Sand AFS 20/25
Silica Sand SiO2 is quartz Hard mineral, SiO2 grades at a 7 out of 10 on Mohs hardness scale making suitable for abrasive blasting sands. And Silica Sand chemically inert and relatively hard mineral making it ideal for use as filtration media.

Silica sand is commonly used as a mineral abrasive for industrial blasting. Though blasting with silica sand can create dangerous dust, exposure is easily avoided by following recommended PPE (personal protective equipment) guidelines and/or by coating the sand with solutions designed to control dust.
Dosage
Silica quartz is often white or colourless, it can come in a wide range of shades. The colour of each sand deposit depends largely on the variety of minerals and rock detritus that make up the resource.
Useful Area
Why Does Silica Sand Make a Great Pool Filter?
Silica sand is made up of the mineral quartz (SiO2) and is
Affordable, effective and easy to maintain (even for large pools)
Eco-friendly, chemical-free, and naturally derived
Naturally odorless and stain-free
However, it’s important to select quality silica sand that is properly washed and graded for pool filtration. Industry best practice is to use #20 Silica Sand which is greater than 95% silica and guarantees an effective grain size of 0.45 to 0.55 millimetres, trapping particles with diameters between 20 and 80 microns (the human eye can see down to 50 or 60 microns). This gradation ensures that when water is pulled into the filter via a pool pump, contaminants like dirt, oil and debris will get trapped in minute spaces between sand grains. Only clean water flows back to the pool.
The wrong type of sand can destroy filtration systems. Regular/brown sands contain impurities (greater than 5% non-silica minerals) that could contaminate your pool water. Additionally, the wrong gradation (too fine, too coarse, or too uniform) will not effectively trap debris and will end up in your pool.
Proper maintenance is important to optimize the life of filtration media and ensure crystal clear pool water. Backwashing your pool filter system at least once a month, and any time the PSI increases to >8-10 lbs over normal baseline, will help extend the life of your filtration sand by preventing contaminant buildup. Regardless, it is recommended to completely replace your filtration sand every 3 to 5 years, as water and contaminants eventually wear down the size and roughness of the sand surface, causing channelling.
How do you know when it is time to change your filtration sand?
Backwash cycles are getting shorter, or are no longer effective

Remarks
Silica sand most commonly used in water filtration, whether processing well water or filtering your tap water. Because of its uniform shape and size, silica sand is an effective filtration bed that consistently removes contaminants from water. Also, it does not degrade when exposed to acidic chemicals.
Silica Sand for Glassmaking : Silica sand is a major ingredient in the production of glassmaking
Silica Sand for Paints & Coatings : Silica sand is used in paints and coatings to improve the overall look and durability of the paint
Silica Sand for Ceramics & Refractories : Silica is an important component in the construction and glazing of all types of ceramics including tableware, floor tiles, wall tiles, and more. Silica serves as the structural backbone of ceramic products helping to regulate expansion and shrinkage, ensuring ceramics dry properly, and improving the overall durability of the ceramic items.
Silica Sand for Construction Materials :
Silica sand used in a number of construction products. Flooring, mortars, cement, roofing shingles, asphalt, and other industrial materials all use silica to improve durability and structural integrity. As silica is resistant to weather, wear and corrosion, it is often used as a caulk or sealant.
Golf Courses & Sports Fields : Silica sand is used for bunkers and greens on golf courses.
