To calculate the size of your liner
Total length of your pond Plus twice the maximum depth plus 2' for an adequate edge.
Total width of your pond Plus twice the maximum depth plus 2' for an adequate edge
Your liner length would be 9'+ 4'+2'=15'
Your liner width would be 6'+4'+2'=12'
For a pond 6 x 9 x 2 you would need a liner approx. 12'x15
To calculate the volume of your pond
Multiply the length x the width x the depth x 7.481
example: pond 6' x 9' x 2' x 7.481= approx. 807 US Gallons
Your pump should be able to process all the water in your pond at
least once every two hours at the minimum
Example: your pond is as the above example:
Your pond is 800 Us gallons
You want at least a 400 Gallon per hour pump
But...before you purchase. Take into consideration your filter size.
For the above volume pond I would put in a 1000 gallon filter. Look at
the circulation of the filter match your pump to it.
Something else to remember. If your having a waterfall you may find it more pleasing to the eye
to run another pump to your waterfall as the pump discharge from your filter, may not be
enough volume to be aesthetically pleasing . Don't exceed the filter circulation to increase
your waterfall appearance , as you will affect the overall efficiency of your filter.
In this case bigger is always a little better. Always get the next largest filter
if possible. It will compensate for the imbalance and will keep your
fish a pond water healthy & beautiful
Sizing a pond for Fish
No more than 10" of fish per 100 gallons of water
Fish Feeding Formula
Reduce feeding fish when the water temperature is 42°F to 65°F
Don't feed fish when water temperature is lower than 42°F
(they can't digest it and you will more than likely kill them)
To calculate electrical power used
Amps x volts= (watts) divided by 1000 x $per Kilowatt hour x 24 hours per day x 30.5 per month
= cost per month
Example: The electrical rating for your pond pump is : 2. 5 amps/115 volts
2.5 x 115=287.5 watts
287.5 Divided by 1000 x 10 cents per Kilowatt hour x 24 x 30.5= $21.04
per month to operate
Always use larger tubing if possible
For every 10' of tubing used add another foot to the lift for friction loss
