The amount of sand needed for a sand filter depends on the filter's size. Generally, you'll need 100 to 200 pounds of sand for a typical pool filter. However, this is just an average. The exact amount will vary depending on the filter's dimensions.
Determining the Correct Amount of Sand
Several factors influence the amount of sand required:
- Filter Size: Larger filters require more sand. A 16-inch diameter filter might need around 100 lbs, while larger filters may need up to 200 lbs or more. Always check your filter's manual for the manufacturer's specifications.
- Filter Media Type: While most filters use sand, some use alternative media, which may have different volume requirements. The amount of filter media (sand or alternative) will affect the overall filtration capacity.
- Filter Tank Model Number: Many filter tank model numbers indicate the tank diameter; for example, Hayward S180T sand filters have an 18" diameter filter tank. You should use the manufacturer's specifications found in the user manual.
It's crucial to consult your filter's owner's manual for the precise amount of sand needed. This manual will provide the specific requirements for your model.

Note: While "freeboard" (space at the top of the filter) is necessary, more sand generally improves filtration, provided it doesn't impede water flow.
