2200 Gal. sand filter. Highly efficient and environmentally friendly way to keep clean water flowing through your above ground pool. It is a more cost effective solution as the pump uses silica sand instead of a traditional filter cartridge. While those cartridges need to be replaced every 2 weeks, silica sand lasts up to 3 years. The sand will trap dirt and debris, but a pre-filter strainer basket catches larger things so that the pump will last longer. The filter also comes with the ChemConnect Dispenser, which maintains clean, healthy water by providing a stable level of chlorine that is evenly dispersed throughout the pool. This product comes pre-assembled, and is compatible with most 300 to 14,400 Gal. (1100 to 54,500 L) above ground pools. Comes with an adapter for pool valves with an outer diameter of 1.5 In (3.8 cm). The sand is not included with this filter - required sand size is #20 silica sand (0.45 to 0.85 mm), approximately 44 Lb. The filter also works wonderfully with Bestways Polysphere Filtration Balls.

Integrate pool system water flow rate (system flow rate): 1800 GPH (6813 LPH) Durable, corrosion-resistant filter tank. 6-position valve allows for easy filter control.
