Pond Pump Size Calculator

Use our pond size calculator to use water calculations to predict the monthly energy cost of our products. For ponds of up to 7 or 8 feet in depth, you will need to know surface acreage. A 200 x 200’ pond is nearly one surface acre in size. For bottom aeration of ponds over 7-8 feet of depth, you will need to calculate acre feet. For assistance with surface acreage water calculations, contact us directly.

How Do I Know What Size Pump I Need for My Pond?

Before you can determine the pump size for your pond, you need to choose your water feature. Each feature comes in a variety of shapes and sizes, so it’s not a one-size-fits-all fix.
