Intex C2500 Krystal Clear Cartridge Filter Pump
Biggest cartridge pump / larger pools — The top of Intex's cartridge line: 2,500 GPH advertised, 1,900 GPH of real filtered flow — enough for a ~15,000-gallon pool. It is the best cartridge option for a larger above-ground pool, and the size where switching to a sand filter starts to make sense.
