What Is No. 20 Silica Sand Used For in a Pool Filter?

No. 20 silica sand is used as the primary filtration media inside compatible swimming pool sand filters. During operation, water is distributed through the filter tank and passes through the sand bed before returning to the pool.

The media bed captures suspended contaminants as water moves through the filter. Proper filtration depends on using the media grade, quantity, and loading procedure specified by the filter manufacturer.

Why the Correct Filter Sand Matters

Proper Filtration
The correct sand grade creates the media bed used to capture suspended debris as pool water moves through the filter.
Correct Water Flow
Properly specified filter media allows water to move through the sand bed while maintaining effective filtration.
Protects Filter Internals
Using the manufacturer's specified media helps reduce the risk of unsuitable material entering or interfering with the filter's internal components.
Check Your Filter's Required Sand Capacity
Sand-filter capacity is determined by the specific filter model and tank size. Some filters require a single 50 lb bag, while larger filters may require several hundred pounds of media. Always confirm the manufacturer's required media weight before purchasing.
