The First Step to Pond Management
A NATURAL APPROACH TO GARDEN POND

Landscaping is an important factor in a resort development.
Landscape design is the key to a successful environment establishment.
A parcel of water has become an integral part to complete a landscape design.
Water management is complex and understanding its effect is vital.
...and garden ponds or pools become a part of our own creation by
...and more ponds..

WHAT IS WATER?
A clear, colorless, odorless, and
tasteless liquid, H2O, essential for most
plant and animal life and the most widely
used of all solvents. Freezing point 0 C
(32 F); boiling point 100 C (212 F);
specific gravity (4 C) 1.0000; weight per
gallon (15 C) 8.338 pounds (3.782

achieve the water quality required and specified by pond
owner but not by nature.

Eutrophicated pond is a nightmare.
Not all green water ponds are bad
but in most or all cases, they are
damaging to intended aesthetic.
Greenish water in man-designed-
made pond is not truly accepted in
the market but by all almighty
command, the quality of pond
water in resort or home garden
has to be . . . . . . . . . . .

The aim of designing a pond is to balance the controllable 'functions'
and be sustainable as to achieve what that is required in a finished product.
This can be achieved by understanding and applying the right natural
components that are controllable.
They are :

1/3. RIGHT WATER FITLRATION SYSTEM
The main problem in pond management is eutrophication.
Eutrophication, a term to describe any excessive nutrient load in water
that leads to the formation of complicated and uninvited characteristic of
water quality such as dark green water.
You need the right filtration system to reduce and control excessive
organic wastes in ponds.
You need a biological filtration system.
Not a mechanical filtration system
Not a chemical filtration system
What is a biological filtration system?
I used to think
bad for me,
.....is a pollution control technique using
..so i gave up
living material (bacteria) to capture and
biologically degrade process pollutants
(excess organic nutrients).
How it works?
....it utilises naturally occurring bacteria
for the purpose of mineralisation of
organic nitrogenous compounds.
In simple terms, it helps to breakdown
dissolved organic wastes into non-toxic
nitrate and nitrogen or technically we
called it..the nitrogen cycle.
What is the nitrogen
The application of the bio-filtration system should designed
to maximum filtration efficiency with minimal maintenance.

The fish that are the masters and the monsters...
ai goromo, goshiki, kohaku, maruten, shiro utsuri, showa ... if these
names are alien to you, so are the Japanese kois. They are the
favourite among all but most useless as a role player in pond
management. High maintenance, disease prone, domesticated
cross-bred fish. These masters that are meant for hobbyist.
The fish nominees for the role as natural pond
managers are . . . . . .

They are the ones that worked for nothing. They sweep
the pond floor, wipe the wall of algae, eat up mosquitoes
larvae, fertilize the plants, occasionally perform for the
family and remain friends.
These are low maintenance fishes and are the most natural
pond keepers. Leave the work to the expertise in the

Does a non-chlorinated swimming pool means....
..........a healthy, safe & chemical-free aquatic environment ?
Which is more detrimental ?
Chemical like chlorine or germs like E. coli ?
Water supports many life forms from
simple unicellular algae to complex
organisms like fishes.
Therefore, naturally it is not meant to
be chemically polluted, especially with
chemical like chlorine. Whatever the
role of water in any architectural
creation of any size, it remains a
responsibility and not just an entity.
Water bodies and their problems are
such will remain a mystery until a
proper understanding between aquatic
ecology and design is achieved and
applied efficiently and correctly.
Pond or pool design and water
management must be addressed from
the very beginning before they become
a burden rather than a welcome
