For an 18x33 foot above ground pool, you typically need a pump with a flow rate of 1.5 to 2 horsepower (HP), or about 2,400 to 3,000 gallons per hour (GPH), depending on your pool's depth and plumbing. This size ensures proper water circulation and filtration for most pools of this size. Always check your pool and filter manufacturer's recommendations to match the pump correctly.
