Pond Calculator

To calculate pond volume in smaller ponds, enter the length,width and depth in feet and click on the gallons, acres, or acre-feet buttons.

For larger ponds, click on acres in the upper left column, then enter the estimated acre size and depth to measure acre feet and gallons.

For natural pond treatments be sure to round up in measurements to avoid underdosing. When using the BioSphere Pro treatment, it's advised to use the total gallon volume of the pond to estimate the dosage required. For instance our One Acre sphere will treat up to one million gallons in volume. The 1/2 acre treats up to 500,000 gallons and the 1/4 acre treats up to 250,000 gallons.
