Pond pump selection Part 1:
Do you know the volume of your pond?
Written by Linda Lin
Knowing the volume of the pond is the first step in getting your pond going.
The volume of the pond will tell you the following
1) size of the submersible pump you need
2) size of filter pump you need
3) the approximate number of fish you can keep
The actual volume calculation methods of ponds of different shapes are listed below
1) Volume for rectangle ponds.
a.) avg. WIDTH(ft) x avg. LENGTH(ft) x avg. DEPTH(ft)x 7.5=
For example: 10ft x 10ft x 2ft =200 (cubic ft.)
200(cubic ft.) x 7.5 gal = 1500 Gallons
b.) Volume for rectangle ponds in litres
Length of pond (m) x Width of pond (m) x Depth of pond (m) x 1000.
e.g. 3m x 2m x 1m then the calculation would be 3 x 2 x 1 x 1000 = 6000
2) Volume for circular ponds.
a.) RADIUS(ft) X RADIUS(ft) X 3.14 X DEPTH(ft)x7.5 = US gallons
b.) RADIUS(m) X RADIUS(m) X 3.14 X DEPTH(m)x1000 = litres
