Maintain clean, soft, and refreshing above ground pool water with the Intex® Krystal Clear™ Sand Filter Pump. The sand filters the water extremely well, and the 6-function control valve enables the pool owner to filter, backwash and rinse, recirculate, drain, and close the system. The built-in 24-hour timer simplifies the process of maintaining a cleaner pool. The strainer basket makes cleaning simple and extends the life of the sand. The Krystal Clear™ Sand Filter Pump has a flow rate of 2,800 gallons per hour, making it ideal for above-ground pools. This pump requires almost no maintenance except for sand replacement every five years.
