Screened Replacement Media for Pool Sand Filters

No. 20 Silica Pool Filter Sand, Screened, 50 lb Bag

No. 20 silica sand is screened filtration media designed for use in compatible residential and commercial swimming pool sand filters. The properly sized media forms a stable filtration bed that captures suspended dirt and debris as pool water passes through the filter tank.

Each bag contains 50 pounds of pool-filter-grade silica sand. Order the number of bags required by the filter manufacturer's media-capacity specification. Do not estimate the required amount using tank diameter alone.

How Many 50 lb Bags Do I Need?

Locate the required sand weight on the filter label, owner's manual or manufacturer specification sheet. Divide that number by 50 and round up to the next full bag when necessary.

Required Sand Weight ÷ 50 = Number of Bags
Filter Sand Requirement 50 lb Bags Required
50 lb 1 bag
100 lb 2 bags
150 lb 3 bags
200 lb 4 bags
250 lb 5 bags
300 lb 6 bags
350 lb 7 bags
400 lb 8 bags
500 lb 10 bags
600 lb 12 bags
Example: A filter requiring 225 pounds of sand needs five 50-pound bags. Four bags would provide only 200 pounds, while five bags provide up to 250 pounds. Add only the amount specified by the filter manufacturer.
Installation Guidance

Protect the Filter Laterals During Filling

Shut off and disconnect power to the circulation pump before servicing the filter. Fully relieve filter pressure and follow the filter manufacturer's disassembly instructions.

  • Inspect the standpipe, hub and laterals for damage
  • Position the standpipe as directed by the filter manual
  • Cover the open standpipe to keep sand out of the plumbing
  • Add water to the empty tank before pouring in the sand
  • Pour the media slowly to reduce the risk of lateral damage
  • Add only the exact weight specified for the filter model
  • Clean sand from the tank opening and sealing surfaces
  • Reassemble the valve and tank according to the manual
  • Backwash and rinse before returning the valve to Filter
Always turn the pump off before moving a multiport valve handle. Changing valve positions while the pump is operating may damage the valve or create an unsafe pressure condition.
Silica Dust Safety

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.
