How do I calculate the amount of water in my pond?
To determine the volume of water in your pond:
(measurements are in feet, and totals are approximate)
Cubic Feet of Water = Length of Pond X Width of Pond X Average Depth of Pond
Cubic Feet of Water X 7.5 = Total volume of water in gallons

For example: A pond 10 X 5 X 2 = 100 cubic feet of water
100 cubic feet X 7.5 = 750 gallons

To determine what size liner you need:
(measurements are in feet)
Max width of pond + (2 X Max depth of pond) + 2 = liner width
Max length of pond + (2 X Max depth of pond) + 2 = liner length

Depending on how often you feed them, you can estimate 1" of fish per 1 square foot of pond.

How many fish you can have in your pond is mostly determined by how you feed your fish. The more often you feed your fish and the lower the quality of food you use, the fewer fish you can safely have in your pond. More fish equals more fish waste, which leads to water quality problems and possibly poor health for your fish.

A good rule of thumb is 1" of fish per 10 gallons of water. So a pond 10' X 5' X 2' deep could have 75 " of fish. (See calculating water volume above.) If the fish are not fed often and has a good filtration system the pond could easily support more.

A healthy pond is clear all the way to the bottom with a thin layer of algae on the bottom surface of the pond.

A healthy pond should be clear all the way to the bottom. A thin layer of algae will most likely cover all the surfaces in the pond. There should be no odor from the pond. Fish should be active from late spring through early fall and will most likely school together.
