VEVOR Pool Filter Balls for Sand Filter, 3.5 lbs, Filter Balls Replace Pool Filter Sand, Reusable Polyester Fiber Filter Media Balls with Wash Bag, for Swimming Pool Above Ground Pool Aquarium Tank

We need to know the size of the filter, or the amount of quartz sand you use, so that we can calculate the amount of fiber balls for you.

The product description states that the filter balls are compatible with "a variety of common filter systems, including sand filters, cartridge filters, and DE filters." However, it does not specify compatibility with all sand filters. For detailed compatibility information, it would be best to consult the manufacturer or a pool professional.

For a 16-inch sand filter, the required amount of filter balls depends on your filter's sand capacity. Add the filter balls directly into the filter tank (do not add water first), then reassemble the filter and start the system according to the pump's instructions.

If the volume of 24 inches is about 11.7m³, 819 kg of fiber balls are needed, which means 511 bags of 3.5 pounds are needed.

4.5 bags are needed.
