Water Garden Pond Pump
Before selecting your water garden pond pump you need to consider the following:
• The total water in gallons of your pond.
• Workload of your pump for maintaining proper circulation.
• Oxygen requirements of fish, plants and other aquatic life.
• Energy consumption required as well as the voltage needs of the pond pump.
Selecting the right pond pump will help reduce the energy consumption of your water garden
pond pump, keep your pond water healthy, and offer minimum maintenance. In the long run selecting the right pond
pump will decrease your overall expenses as well.
Measuring Your Pond Water in Gallons
Knowing the total gallons of water in your pond will help to insure that the pump helps to maintain the proper
amount of water circulation. Too little circulation will create stagnant water and low oxygen as well as a lack of
proper filtration.
Stagnant water is an invitation for pond scum, excess mosquitoes and other unwanted bacterial growth. Low
oxygen is detrimental to your fish and other aquatic population including your plants.
Good circulation is achieved when your pond water is total circulation of your pond water once every two
hours.
To calculate the total water gallons of your pond use the following mathematical measurements:
For circular ponds calculate using the following:
3.14 x Radius x Radius x Average Depth x 7.5
For the square or rectangular type ponds:
Length x Width x Average Depth x 7.5 = Approximate Gallons
You can also consult with a pond specialist to help with more complex designs. When in doubt always calculate
for more rather than less.
Water Work Load - Pushing and Pumping Your Pond Water
There are several things to consider for the workload requirements of your pond pump. Most pumps contain a
flow chart to help you figure out the energy consumption at certain head heights as well as the gallons per hour it
will be able to circulate.
However, there are many factors that will create more or less workload. The height of your water features,
the depth of your pond, the length of the tubing, as well as angles of the tubing, added adapters and
bulkheads etc...
Before you consult with your supplier, gather up as many of these details as possible so that the supplier can
help you calculate the needs of your pond.
Oxygen Requirement's on Your Water
Garden Pump
If your pond is more of water garden the workload of your pump will be much less than if it's full of fish. For
fish ponds, five inches of fish per five gallons of pond water is a good measurement.
The more gallons of water per fish the better. Also, if you have small fish, remember they will be getting
bigger every year so it is best to calculate their possible size per gallon rather than their temporary size.
It is valuable to keep the fish load below the accepted equation.
Energy Consumption of Your Water Garden Pond Pump
Generally pond pumps are designed for 110V, which can be plugged into most outlets in the United
States. A 230V pump requires a different outlet and you will want to make sure your home is properly set up to
accommodate this type of energy consumption.
The higher the wattage the more energy is consumed and the higher your electric bill will be. Pond pumps
never stop working so this may very well be the first thing you need to consider when deciding on how big your pond
will be as well as how many fish and other wildlife it will be caring for.
