Avoid Creating or Breathing Airborne Dust
Silica sand can produce airborne dust during handling. Open and pour the bag carefully in a well-ventilated area. Avoid dropping the bag, dry-sweeping spilled material or using compressed air to clean it up.
Avoid breathing dust and prevent contact with the eyes. Review the product packaging and applicable safety data before handling. Use appropriate eye protection, dust controls and respiratory protection when required by the product label, work conditions or applicable regulations.
Frequently Asked Questions
What is No. 20 silica pool filter sand?
No. 20 silica sand is screened granular media used inside compatible swimming pool sand filters. Water passes through the sand bed, where suspended dirt and debris are captured before the water returns to the pool.
How much sand is included in this listing?
This listing includes one 50-pound bag. Increase the Shopify order quantity to purchase additional bags.
How do I know how many bags my filter requires?
Check the filter's model label or owner's manual for its required media weight. Divide the required weight by 50 to calculate the number of bags. Round up when the result is not a whole number, but add only the specified weight to the tank.
Can I use regular play sand in my pool filter?
No. Play sand and general-purpose sand may contain particles that are too fine, too coarse or inconsistently sized for the filter. Use only the media grade specified by the filter manufacturer.
Can this be used in any brand of sand filter?
It may be used in filters whose manufacturer specifically requires No. 20 silica sand. Confirm the required media type, particle range and total fill weight before ordering.
Can this sand be used in a cartridge or DE filter?
No. Cartridge and diatomaceous-earth filters use different filtration systems and do not accept a sand bed. This media is intended only for compatible sand filters.
Should I fill the filter tank completely with sand?
No. Add only the specified media weight. The open area above the sand bed is required for proper water distribution and expansion of the media during backwashing.
Why is water added to the tank before the sand?
Adding water cushions the sand as it enters the tank and helps reduce the risk of damaging the internal laterals or underdrain assembly.
Do I need to backwash new filter sand?
Yes. Follow the filter manufacturer's startup procedure, which typically includes an initial backwash followed by a rinse cycle before placing the valve in the Filter position.
Is pool filter sand returnable?
No. This heavy filtration-media product is non-returnable. Confirm the required media type and quantity before placing the order.
Not Sure How Much Filter Sand You Need?
Locate the manufacturer, filter model number and required media weight before ordering. The filter label or owner's manual should state the correct quantity.
