VEVOR Sand Filter, 24-Inch, 65 GPM Above Inground Swimming Pool Sand Filter System, with 7-Way Multi-Port Valve, Backwash, Rinse, Recirculate, Waste, Winter, Closed Modes, for Above In Ground Pools

For a 24-foot round above-ground pool with a 50-inch wall height (which holds approximately 13,500 to 14,000 gallons of water), you will need a 22-inch to 24-inch sand filter paired with a 1.0 HP to 1.5 HP pool pump to ensure the water cycles completely and efficiently.

Sand Capacity: It requires 130 kg to 145 kg of sand. In US measurements, this translates to roughly 285 lbs to 320 lbs of sand (typically 6 bags of standard 50 lb pool sand). Type of Sand: VEVOR recommends using #20 silica sand (0.45mm–0.55mm or roughly 0.8mm quartz sand) for optimal filtration.
