You can calculate the volume of water in your pond using the following formulas:
Rectangular Water Features:
length x width x depth x 7.5 = Gallons
Circular Water Features:
diameter x diameter x 5.9 = Gallons
Oval
length x width x depth x 6.7 = Gallons
These formulas are important when choosing a water pump. For best pond health, your pump should move the entire volume of your pond in one hour. For example, a 900 Gallon pond or water feature should have at least a 900 GPH pump.
