Submersible pumps
Submersible pond pumps, sized by GPH (gallons per hour) are placed directly in your koi pond, and eliminate the noise that external pond pumps can make.
Flow rates range from 250 GPH to as high as 4,100 GPH for a larger waterfall pump. Generally, the ideal pump will circulate the total volume of the pond at least once per hour. For example, if you pond is 500 gallons, you would want to go with at least a 500 GPH pump.
