For example, if you have a 1000 gallon pond, then you need a pond pump rated at a minimum of 500 GPH. If your pond has a skimmer or waterfall, the water should be turned approximately once every hour. Therefore, if you have an 1800 gallon pond, you will need an 1800 GPH rated pump. via
How do I know what size pond pump I need?
The pond pump should circulate the water at least once per hour. To determine the volume of your pond, multiply the length x width x depth. For every square foot of volume there are 7.5 gallons of water. So, a pond that has a volume of 50 cubic feet will contain roughly 375 gallons of water. via
