Important Pond Calculations
To determine the size of a pond liner:
Length + 2 x depth + 2 x 1½ ft (for overlaying outside edges under your coping of rocks.
For example, to create a pond measuring 8 feet by 10 feet by 2.5 feet deep, you will need a liner measuring 16 by 18 feet.
Length=(2½ ft x 2) + 10 ft + 3 ft =18'ft
Width=(2½ ft x 2) + 8 ft + 3 ft =16 ft
We cut liner to fit your dimensions. It is wise to dig your pond and then re-measure.

To calculate the volume of a pond:
Length x Width x Depth x 7.48 = Pond Gallons (use measurements in feet) If you have a circular pond, multiply the dimensions by 5.9

To calculate the size of a pump:
Pond Volume/2 = Pump Size
(The pump should circulate the pond's water volume at least once every two hours. Add to the pond's volume if you are using a fountain or waterfall. And remember, each foot up you are pumping reduces the flow significantly---so check the boxes to see what the actual flow is!) Also the more fish you have, the greater the need for oygen.
