Little Giant PondWorks pond pumps are designed for continuous operation for table top displays, fish ponds and Koi ponds, small and large statuary, ponds, fountains, waterfalls, streams and water gardening. We offer a complete line of submersible pumps designed to operate safely and silently while completely submerged in your pond.
The size of the pump you will need will depend on how high you want your fountain to be and how much water you will need to circulate. For this reason, it is important to know the gallon capacity of your pond. The water in a basic pond should be turned at least once an hour, which means a 500 gallon pond should have at least a 500 GPH (Gallons Per Hour) pump. To calculate the gallons in your pond, follow this formula: Length x Width x Depth x 7.5 = Gallons.
