Here are some tips and ideas that may help you in the
planning, construction and upkeep of your pond.  We 
will be updating them regularly and we encourage you 
to send us any tips that you may have.  We will post 
them here so that fellow ponders can learn from your 
experiences.
They are in no particular order except for the first 
three.  They deal with important safety issues. 
CALL BEFORE YOU DIG
1-888-258-0808 is a toll free number available for on
sight surveys.  This is a free service in which a 
representative of your local utility companies will 
come out to your house and mark the location of all 
underground lines and cables.  In most states, this 
is required by law before any digging, drilling or 
excavation is done.  This also exempts you from any 
legal or financial responsibilities, should a line be
hit that was either not marked or mis-marked.  This 
phone number is valid and operated 24 hours a day in 
the United States and Canada.  They do, however,   
require 48 hours notice.        
GROUND FAULT CIRCUIT INTERRUPTER
Known also as G.F.I., these are electrical outlets 
that are usually found in kitchens and bathrooms and 
other areas where electricity is likely to come in 
contact with water.  They are designed to shut off 
the power at the first sign of an electrical short, 
usually 1/40th of a second or less, which is long 
before an injury can occur.  Please make sure all of
your outdoor lighting, pumps and fountains are 
plugged into a G.F.I. outlet.  They are available at 
any home improvement store for around $10.00.
PONDS AND CHILDREN
There will most likely be times when you will have 
small children around your ponds, whether it be your 
own kids, your grandchildren, etc.  Water by itself 
is a natural attraction for any small child, not to 
mention the added enticement of fish and flowering 
plants.  Never leave a small child unattended around 
your pond.  Apply all the same safety rules to your 
pond that you would to a swimming pool.       
LOCATION, LOCATION, LOCATION
Two important factors to consider before deciding the
location of your pond are...
- 
- A.  Run-off; Heavy rains can wash fertilizers and
pesticides from your lawn into your pond.
- 
- B.  Sun exposure;  Most flowering plants need a 
certain amount of sunshine each day in order to 
produce flowers.  Water Lilies for example, need at 
least 6 hours of full sun in order to bloom.  On the 
other hand, too much sun will promote algae growth 
and high water temperatures in the summer.     
POND CALCULATION
Location has now been established, you probably have 
a general design in mind of what you want your pond 
to look like, there are several other things that can
be very useful before actual construction begins.    
- 
- FOR EXAMPLE
- 
- A.  How much liner will be needed for the size 
and shape of your pond?
- 
- B.  Knowing the capacity of your pond in gallons 
will help you determine the size of the pump and 
filter that will be needed.     
- 
- C.  Knowing the total surface area will help you 
calculate the number of fish that your pond can 
safely accommodate.
- 
- D.  How many and what types of plants will be 
required to maintain an ecologically balanced 
environment for the size pond that you have chosen.
- 
- All of the answers to these questions and more 
can be found at Chuck Rush's pond calculator.  It is a very 
valuable tool for both those who are in the planning 
process as well as those with established ponds.  You
can also find his home page in our "favorite links" 
section.  
FILTRATION
Your pond is dependent upon you to provide proper 
filtration.  Mother nature provides this in a natural
setting with plants and micro-organisms, which live 
in the soil.  In an artificial environment, such as a
backyard pond, there are special needs.  Chemicals, 
such as ammonia and nitrites, build up to harmful 
levels, this is why a  
biological filter is so important.
CONSTRUCTION TIPS  
- 
- A.  Pond depths;  Ponds should have various 
depths, allowing fish to have a choice of different 
water temperatures.  A typical pond should vary from 
18 to 32 inches deep to ensure the survival of fish 
and plants through seasonal changes.               
- 
- B.  Underlayment;  It's important to have a 
protective barrier between the liner and the soil to 
act as a cushion.  A few good options are sand, old 
carpet or even layers of dampened newspaper.  
   
-   
- C.  GFI and pump placement;  The pump should be 
located at the far end of the pond, opposite from the
waterfall or the filter.  This will provide full 
circulation of the water. Some pumps have short 
cords, therefore, the electrical outlet, (GFI), needs
to be at the far end of the pond as well.  
Plan on using a pump that will move the total water 
volume of the pond at least one or two times per 
hour.
 
You can avoid having the pump cord exposed by placing
a piece of 1/2" pvc under the rocks leading up to the
outlet.  Cut the plug off of the cord, feed it 
through the pvc and replace the end with a weather 
proof plug.   
Silicone and water.  
Building a filter will require using silicone on the 
threaded fittings.  Most silicone is not rated for 
under water use.  (This was news to me)  When 
purchasing yours, be sure to read the fine print.  
There is a marine grade silicone on the market but it
can be hard to find.  I recommend using a small 
squeeze tube of aquarium silicone which can be
purchased at almost any pet supply store.   
NAMING YOUR FISH
