Bestway - Flowclear Sand Filter (1500Gal)

●The Pump Uses Silica Sand (Not Included) Instead Of A Filter Cartridge Which Is Far Morecost Effective Than Running A Traditional Filter Pump System.● Where A Filter Cartridge May Need Replacing Every 2 Weeks, Silica Sand Only Needs To Be Changed Once Every 3 Y. ●The Pump Works By Draining Pool Water Through A Hose And Into The Filtration System.
