Steps For Building A Pond
Pond
Planning Sequence
Designing
a Pond - Too many people get caught up in
designs and plans for their dream pond and in the end will
likely spend years planning it, or not build it at all. It’s
very common in landscaping that over designing a natural pond,
results in:
1. The pond not getting built for years or never built
2. It is too symmetrical and unnatural (formal)
3. It is built in the wrong location
4. The cost and perplexity increases substantially
The best advice we can give our customers is to skip the designing
phase and move directly to site preparation with a clear understanding
of their objective.
Let’s
start by stating a few simple facts:
Size
· Ponds can be built to any size and in any sized yard
· Bigger sized ponds are easier to maintain
· Greater filtration
and ecosystems
· Minimal cost difference
and labor between pond sizes
· Most first timer’s
wish they had built their pond bigger
Difficulty
· Pond Kits take all the guess work out of building
a pond, by; containing all the parts needed based on size,
simplifying procedures and assembly, and providing detailed
step-by-step, easy to understand instructions
· With a pond kit, 2 to 3 inexperienced adults can
build a beautiful (leak-free) pond (8’ x 11’)
in just 2 weekends
· Most ponds are built without need of; heavy equipment,
hauling away waste material, or bringing in sand or soil
Location
· Ponds should not be built in a low-point (where water
gathers) without first fixing the existing drainage problem.
Determine
Your Objective - The homeowner’s want
to enhance their backyard and family lifestyle with a natural
pond and water feature. They will want to be able to enjoy
their pond as much as possible (see it, hear it, be close
to it, entertain by it) and don’t want to spend much
time or work maintaining it.
Site
Location and Preparation - People have the
tendency to think where a pond would look best or “fit
in” as opposed to, where can they get the most enjoyment
with it. So, a common mistake is to build the pond in a corner
or a distance away from where they now spend time outdoors.
The farther the pond is from the house and deck or porch,
the less they will visit it.
To get the maximum enjoyment from a pond and waterfall it
should be built as close to their living areas as possible
(outside patio or deck and indoor favorite rooms). Waterfalls
are the focal points of most ponds and should face the house
allowing it to be heard through open windows and viewed from
both indoors and outdoors.
1.
Start by stepping 1 foot off your patio or deck and place
a garden hose down in a kidney or other natural shape (informal)
and then place a chair on the opposite side (waterfall perspective).
2. Sit in your favorite deck chair and view your mock-up and
imagine it as a beautiful pond alive with color and sounds.
Can you almost reach out and touch it? Is this where you want
to be when the sun goes down and you’re finally on your
own time?
3. View your mock-up pond from inside the house or covered
porch. Can it be seen from the kitchen? Can it be seen and
heard from your dining room or restful place? Will your bedroom
overlook it and afford yourself the luxury of falling asleep
listening to the soothing, restful sounds of cascading water?
Does someone in the house spend long times in one room (shut-in,
work-from-home, etc.) that could take advantage of the pond
location?
4.
Do you want to set your waterfalls back beyond the side of
the pond by using a stream? Try moving the chair back 5’,
10’, 15’ and view the mock-up from the patio and
house.
5.
Is the pond big enough? Are the pond and stream (if any) in
proportion to each other? Can you still get around in your
yard easily with the pond where it is? Make adjustments in
size and shape and length of stream (if any).
6.
Mark down the measurements of the pond and stream you want
and then contact us and let us help you find the best pond
kit to suit your needs and budget.
7.
Ask us to recommend a submersible and aboveground lighting
system so you can enjoy the pond in the evening. Stock up
on the few tools you might need for the job (2 spades and
a good wheelbarrow).
8.
Take your new pond kit home and open it up. Review the instructions
and DVD (if included) for a better idea of how easy it will
be to build and a clearer understanding of the rocks and gravel
you will use.
9.
Go to a rock and gravel supply yard and see what they have
available to build your pond. Order your rock and gravel needs
and arrange delivery.
10.
Review the pond kits 20-step construction process and 20 components.

Proper Liner Sizing
—
Calculating Liner Size —
2
x pond depth + maximum pond length
+ 2 foot (1’ min.) extra = liner length
2
x pond depth + maximum pond width
+ 2 foot (1’ min.) extra = liner width
Example
liner for a 11’ x 16’ pond that is 2’
deep:
(2 x 2’ + 11’ + 2’ = 17) x (2 x 2’
+ 16’ + 2’ = 22’)
= 17’ x 22’ liner size |
Liner
Tips
45
mil EPDM liner is sold from rolls of 50’ and 100’
lengths with widths of 10’, 15’ and 20’.
In the above example (17’ x 22’ liner size), the
customer would need to purchase a 20’ x 22’ liner
size.
Customers should be encouraged to over-size the liner requirements
to allow for slight measurement errors. If the liner size
used is found too short for the customers project, backfilling
to reduce the pond size should be suggested first. If this
is not an option, then suggest extra liner and Cover &
Seal tape.
Pond
kits come with an exact size pre-cut liner and customers
should be advised to build a slightly smaller diameter pond
than suggested in the kit, to ensure enough liner for the
project.
45
mil EPDM liner has a 20-year warranty for cracks and damages
caused by sun exposure (UV), but the warranty only applies
if the liner is fully covered (rocks, gravel, soil, etc.).
Water
Volume Formulas
| —
Approximate Gallons of Water in a Pond —
Avg.
length x avg. width x avg. depth x 7.48
(gal. in a cubic foot of water) = total gal. in pond
Example pond: 11’ x 16’ x 1.5’ x 7.48
= 1975 gal.
—
Approximate Gallons of Water in a Stream —
Length
x width x .25 x 7.48 = gallons in a stream
Example
stream: 3’ x 15’ x .25’ x 7.48 = 84
gal. |
The
total gallons of water in your pond is needed for determining:
pump and filter size, administering water and fish treatments
and for fish quotas.
| —
Effective Pond Water Volume —
Effective
Water Volume calculates environmental factors and should
be used to determine the proper pump and filtration
system. Use the following:
¤
Avg. pond water depth is less than 2½’:
add 25%
¤ Pond is located in full sunshine: add 25%
¤ Pond is located in partial sunshine: add 12.5%
¤ Pond is located in northern climate: add 0%
Example
Edmonton pond: 2000 gallons, avg. 2 ft.deep, and in
partial sun - would have an effective pond water volume
of 2750 gallons (2000+37.5%). |
Fish
Stocking Levels - The above information is based
on a maximum fish stocking level of 100” of fish per
1000 gallons of pond water. Higher fish levels will require
a larger pump and filtration system.

Choosing
the Proper Pump
Considerations
when choosing the proper pump:
1. Water volume the pump will be expected to move
2. Desired flow rate for the waterfalls and stream
3. Width of the waterfall spillway and stream
4. Height and length the water needs to be pumped
5. Pipe diameter with number of fittings and elbows
6. Cost, flow rate, voltage, and energy consumption
Maximum
Pump Flow Rate
- measured in “gallons per hour” (gph), this number
provided by the manufacture is the maximum gph the pump will
push water out of its discharge. This number decreases as
soon as it leaves the discharge and begins to be pushed through
a pipe.
Shut-off
Height
- is provided by the manufacturer and identifies at what height
(in feet) the pump will cease to push water.
Static
Head
- is the overall height that the pump will have to push. (Measured
from the pond surface up to the waterfall spillway.)
Friction
Head
- is the amount of resistance caused by the piping. (Affected
by pipe diameter, length and type of pipe and amount of fittings.)
Total
Dynamic Head (TDH)
- Elevation(ft) + Friction(ft) = TDH for a particular pump
size. TDH is a calculation which determines how much water
the pump will actually push under a given circumstance.
Several
TDH calculators are available on the web, such as at: www.pumpworld.com.
· Most backyard pond waterfalls are built 2’-5’
high
· Good waterfall pumps are designed for minimal loss
within the first 5’ of rise and 40’ of pipe length
· Minimum flow rate for the waterfall width (weir)
is 100 gph per inch of weir width
· Best flow rate is 1500 gph per
weir foot
· Minimize pipe resistance:
· Use flexible PVC pipe to reduce
fittings used
· Do not use a smaller pipe diameter
size than the diameter of the pumps discharge
· 10’ of horizontal pipe length = 1’ vertical
head rise
· For proper filtration the pump needs to circulate
the entire pond water once every two hours
· For optimum filtration or for smaller
ponds the circulation rate should be once every hour
Example
pump sizing for a planned pond of:
Pond
dimensions: 11’ x 16’ x 2’ with 10’
stream
1.
Water volume: 2000 gal
1.a Effective water volume: 2750 gal
2. Waterfalls and stream flow rate: 1500 gph/weir 1’
3. Width of the waterfall weir: 1½’ = 2250
gph
4. Pipe length: 26’ say 30’. Waterfall height:
4’
4.a 30’ of pipe = 3’ rise. 3 + 4 = 7’
rise (static head)

| Pump
Types |
Aeration
Pumps
Supplementary oxygen supply for existing filtration systems
in ponds. Aids poor filtration systems and high fish levels.
Temporary stand-alone air supply, used with an air stone
to disperse air bubbles. Used in aquariums and for visual
effect. |
Statuary
Pumps
Designed for fountains and other small water feature applications
not requiring water filtration. Pump ratings (GPH) are
primarily used for obtaining proper head height flow for
a fountain. Will oxygenate water but does not filter it.
Can be used with aquatic plants to provide filtration
for small goldfish. The pumps are also used in hydroponics
and aquarium settings. |
Submersible
Mag-Drive Pumps
Multi-use, high-resin pumps used to power fountain heads
and waterfalls. Used with a mechanical or biological filter
(or both), for proper filtration of water gardens (containers,
preformed, small ponds with liner). Magnetic drive pumps
are energy efficient and designed to run continuously
without oil or seals that may fail. |
Submersible
High Volume Waterfall Pumps
High volume pumps used to power waterfalls. Generally
used with a skimmer and biological waterfall filter, for
proper filtration of ponds. Heavy duty, air or water cooled
pumps with stainless steel motor shafts, designed to run
continuously. Upright discharge design, eliminates elbow
and reduces friction loss. |
Filtration
Q & A
Q.
What is a Pond Filtration System?
A.
The mechanical and biological
filtration of the entire pond water volume as it is constantly
circulated and oxygenated. Good systems will entirely circulate
every hour.
Q.
When do you need a Pond Filtration System?
A.
Primarily, when keeping fish or when organic debris (leaves,
pine needles, grass cuttings, etc.) settle and rot in the
bottom of your pond, causing poor water quality.
Q.
When do you not need a Filtration System?
A.
When you are not keeping fish, situations where frequent
water changes are carried out or when using small containers
with aquatic plants.
Q.
Can you keep fish without a Filtration System?
A.
Yes. Small (1 inch) Goldfish can survive in a bowl
of water indoors where the sun's UV rays and wind blown organic
matter is absent. Goldfish can be kept outdoors in containers
of 30 gallons or less of water, providing plants cover 80%
or more of the surface area and frequent water changes are
performed. Koi require plenty of oxygen and a good filtration
system!
Q.
Are small ponds easier to maintain?
A.
No. Actually larger ponds are easier to maintain
as the filtration system will be larger and the biological
filtration will be less affected by disturbances. Aquatic
plants can be removed from their pots and have more room to
grow.
Small
ponds require more frequent maintenance but can be just as
rewarding as large ponds as long as you think big on the
filtration system (including plants).
Filtration
- Types
Backyard
ponds are an enclosed, unnatural environment, which lacks
the basic filtration qualities found in natural bodies of
water and streams. Backyard ponds are overburdened with fish
waste, decaying leaves and grass, disturbed silt, organic
sludge and the effects of sun exposure on shallow water. A
pond would quickly become toxic for all life if not for algae,
which feeds off the excess nutrients. But then, we don't want
the resulting green water brought on by an explosion of suspended
algae.
There
are four basic types of filtration which can aid the water
gardener in obtaining a healthy ecosystem and clear water:
Natural, Mechanical, Biological and Chemical.
Natural
- Rocks and gravel provide a large surface area for beneficial
bacteria to colonize. Plants are an excellent source for filtering
water by; trapping and feeding-off of excess floating nutrients,
providing surface area for bacteria to attach and by shading
the pond from full sun.
Mechanical
- Is the physical removal of suspended material by straining
the pond water and removing the debris.
Biological
- Is the use of beneficial bacteria to convert organic waste
compounds (Ammonia) into toxic Nitrite and then into Nitrate,
which is far less toxic.
Chemical
- Chemicals have no place in today's ecosystem ponds other
than Activated Carbon, which is effective in removing dissolved
organics (tea colored water).
Filters
are essential in obtaining water quality and for our
backyard ponds to thrive with life and color. Two types
of filter processes are needed to maintain a healthy
pond: Mechanical
and Biological.
|
 |
Biological
Filters
provide a large surface area where beneficial bacteria
can colonize and perform their part in the "Nitrogen
Cycle". Circulated water flushed through a biological
filter provide the necessary nutriment and oxygen for
bacteria to thrive.
Mechanical
Filters
will trap solids before they can clog the pump (pre-filter)
and will limit the amount of solid deposits in a biological
filter. |
| Aquatic
Plants |
"It's
just a hole with rocks and water without plants" |
Our
backyard ponds are an enclosed ecosystem that need
our help to remain healthy. Adding aquatic plants
to our ponds will beautify them but it is the ecological
benefits to an enclosed system that should most influence
our aquatic selections. Aquatic plants have 4 main
grouping (water lily, marginal plants, submerged and
floaters) and each group have their own unique benefits
to our ponds. |
| |
What
is the difference between a Water Garden and a Pond?
There really isn't a difference between the two, but
the water garden sounds tropical with more exotic
colors, fragrances and flowering plants. A pond sounds
more desolate and lacking vibrant colors but teaming
with microscopic life below and at the surface. Bulrushes
and tall grasses with visiting birds dominate our
natural local ponds and landscape. A water garden
is designed to please and arouse our senses and engulf
us within an outdoor room of pleasure. |
| |
Today's
water gardening craze combines the flavor of tropical
water gardens with locally available plants in a natural
pond setting. The benefits of this combination is
the spectacular color and beauty to behold along with
a healthy ecosystem to support it. Understanding the
main groupings of aquatic plants and the roles each
have to play in our backyard ponds can enhance our
overall enjoyment in water gardening. |
| |
Aquatic
plants are grouped based on their planting depth in
a pond and ponds are designed with shelves for planting.
The first shelf in a pond is designated for Marginal
plants, the second shelf for Water Lily
like plants, the bottom of the pond for Submerged
plants and Floaters on the pond's
surface. |
| |
|
| Water
Lily |
|
Lilies
are the most popular aquatic plants and are the reason
why so many of us build a pond. Over 50 varieties
of water lilies exist with a wide range of styles
to choose from: |
·
Bold colors: Red, Pink, Yellow, White |
·
Leaf pad diameter sizes from 2 inches to 2 feet |
·
Varieties: Hardy, Tropical, Miniature |
·
Day-Bloomers: Typically from 10 AM and 5 PM |
·
Night-Bloomers: Typically from 8 PM and 10 AM |
| |
Water
lilies are planted at a depth of 12" to 18". The second
shelf in a pond is 12" to 20" deep and is designed
for water lilies and similar type plants. For growth
potential, the lily can be removed from its pot and
planted in a pocket on the second shelf. For our climate,
many people will leave it in its pot for easy removal
at the end of the season. |
| |
Aquatic
plants play a vital role in the pond’s ecosystem
and water lilies are of particular benefit: |
·
Lily pads shield a portion of the pond from the sun
and provide ideal coverage for fish |
·
Competes with algae for excess nutrients |
·
Stems offer a large surface area for beneficial-bacteria
to cling to and help purify the water |
| |
For
wintering, cut off plant material and store the moist
root in a bag in the fridge or cold room, or in a
jar of distilled water in a cold room. |
| Marginal
Plants |
The
marginal classification includes many different plant
species, from grasses and rushes to a multitude of
flowering plants and colors. Both local and warmer
climate marginal plants adapt very well in our backyard
ponds. |
| |
Marginal
plants add life to a pond with their splendor
of color and texture. They attract insects, small
animals and birds to the pond as a habitat and for
safe cover when feeding or bathing. Marginals are
planted at a depth of 1" to 8" on the first shelf
of a pond. They help to soften the rock edges of the
pond and provide a transition from the pond to the
landscape. |
| |
Aquatic
plants play a vital role in the pond's ecosystem and
marginal plants will be of the most benefit if they
are removed from the pots and planted in loose gravel.
This allows the roots to trap waste sediment and compete
with algae for excess nutrients in the water. Marginal
plants provide some shade from the sun. |
| |
For
wintering marginals, cut back plant material before
rotting takes place and leave the plant in the pond.
They can also be cut back and brought indoors. Irises
and some other flowering varieties rarely survive
our winters and are treated as annuals. |
| |
|
| Submerged
Plants |
Submerged
plants are likely not at the top of your plant
list for the new pond. They're rarely seen at the
bottom of the pond and few varieties flower. Most
submerged plants do not root and can get caught in
mechanical skimmers and filters. Rock
stream bed edges are great for holding submerged and
marginal plants. |
| |
Ecosystem
benefits of Submerged Plants: |
| 1.
They act as nutrient sponges, trapping and feeding off
of fish waste and organic sediment |
| 2.
Compete with algae for available nutrients |
3.
They produce much needed oxygen during the day
(Note: All
aquatic plants consume oxygen at night.) |
| 4.
Acts as a natural media for spawning fish |
| 5.
Provides excellent habitat for small fish and pond life
|
| |
Submerged
plants should be treated as annuals and need to be
removed at the end of the season. If you're still
not sure that submerged plants are helping make your
water crystal clear, shake a plant on the bottom of
your pond and observe all the harmless flakes which
were once toxic fish waste and other decaying matter.
|
| |
|
| Floating
Plants |
Water
Hyacinth, Water Lettuce and Frogbit are the most common
of the floaters group. Water Hyacinths are instrumental
in achieving a healthy pond environment with clear
clean water. |
| |
The
hanging roots of floaters are the key in filtering
water and starving-out algae. The roots trap waste
and organic sediment and extract the nutrients from
it. Beneficial bacteria colonizes on the roots and
break down Ammonia (toxic fish waste byproduct) into
Nitrites and into less toxic, Nitrates (Nitrogen Cycle). |
| |
Floating
plants can be placed anywhere in our ponds including
waterfalls and streams. For the pond ecosystem, water
hyacinth work best in the biological filter because
of the high water flow and oxygen levels. They can
be a nuisance by winding up in our skimmers and it
takes some fiddling to keep them out. Fishing line
can be used to hold the plants in the biological filter.
They can be tucked into stream and pond edges easily.
Koi will entertainingly push floaters around the pond
feasting on trapped fish food, snails, algae and other
pond delicacies. |
| |
|
| Plants
To Avoid In and Around Your Pond |
| |
Some
plants in our backyard landscapes can be poisonous
to aquatic life. The following plants should not be
planted where fish can access any portion of the plant
for ingestion: |
| |
Azalea
(Rhododendron species)
Black Locust (Robinia species)
Buttercup (Ranunculus spp.)
Caladium (Caladium xaiitliosoma)
Castorbean (Ricinus communis)
Chokecherry / Cherry (Prunus spp.)

Understanding
Algae
Imagine
what would happen if you tilled a pond-sized area of soil
that receives full sun, fertilized it with nitrates, watered
it and planted a few small shrubs. It’s more than likely
that weeds would soon appear and if left unattended, it would
become an eyesore. To correct the situation, a gardener would
deprive light to the weeds (weed barrier, mulch, etc.) and
then plant a greater variety of types to fill out their bed.
Take
the same situation with a pond that is under full sun, likely
overstocked with fish (exceeding 10” of fish per 100
gallons of water), excess nitrate nutrients in the water and
just a few aquatic plants. Algae which is always present in
a pond, will naturally thrive in this situation. As the algae
population increases, they will be producing oxygen during
the day but depleting oxygen during the night which will eventually
change the water chemistry.
Wide
pH swings between day and night can cause fish stress or loss
and kill all the algae (crash). It’s terrible to lose
fish, but at least the unsightly algae is gone. Or is it?
The dead algae on the ponds floor will be consumed by anaerobic
bacteria (bad) which live in the depths where oxygen is at
a minimum. As the toxicity of the pond worsens, new algae
will exponentially multiply causing what is commonly referred
to as an “algae bloom”. The whole cycle is destined
to be repeated again and again.
Correcting
the situation will take time, patience and some of the same
gardening strategy used to limit weeds; deny sunlight and
add more plants to compete for nutrients. This pond will require
a little more help.
Fixing
a Sick Pond:
Treatments
to help your pond will only work if the water is free
of chlorine and chloramines and the pH is within an
acceptable range. |
Step
1. Water Quality
a.
Detoxify the pond water with a de-Chlorinator.
b. Test the pH of the pond water with a test strip
or other kit.
c. Gradually raise the pH, lower the pH or stabilize
the pH.
d. Increase the oxygen with an aerator. This will help;
stabilize the night-to-day pH swing, reduce the risk of algae
blooms, reduce the anaerobic (bad) bacteria and help the nitrifying
(good) aerobic bacteria.
Step
2. Water Clarity
a. Seed the biological filter with beneficial bacteria
and repeat this process for 4 to 7 days. Continue adding beneficial
bacteria as described by the manufacturer.
b. Add water lilies and floating plants to help shade the
pond from the sun.
c. Add marginals and aquatic plants to compete with algae
for nutrients and to clean the water.
d. Add barley pellets to help balance the pond.
e. Remove string algae by hand and practice patience.
Algae
provides over 85% of Earth’s oxygen and 80% of its food
source. It will always be in our ponds and will be a valuable
food source for almost everything living in our ponds. Once
we understand that there is no “quick fix” to
eliminate algae and make the water crystal clear, we can relax
and allow nature to take its course.
Other
effective water treatment products are available which aid
in balancing the pond or for temporary relief.
Beneficial
Bacteria
From the moment you add water to your pond, beneficial bacteria
will be busy doing its job in the Nitrogen
Cycle. Adding a bacteria/enzyme product to our ponds
as routine maintenance will speed up the process and ensure
the number of bacteria (billions) will be effective.
The
biological filter is designed to house colonizing bacteria
where the conditions are best (large surface media to attach
to and well oxygenated) to do its job. Think of the mechanical
filter (skimmer) as a garbage dump and the biological filter
as the Recycling Station.

Glossary
of Terms
Five
minutes every two weeks is all it should take you to maintain
your pond. Empty your skimmer net of floating debris and add
the recommended amount of beneficial bacteria and you're done.
You don't have to be an expert to look after your pond, but
knowing relevant terms and how it all works will definitely
help.
The
terms provided below will help you to understand the pond
ecosystem which unfortunately includes toxins and halogens
that can harm your fish and lead to an imbalanced pond.
Aerobic
- Living or occurring only in the presence of oxygen: aerobic
bacteria.
Ammonia
- (NH3), is the most toxic of the nitrogenous (nitrogen containing)
pollutants. Most ammonia enters the water when it is excreted
by the fish from their gills during metabolism. The rest comes
from the breakdown of pollutants and food. Ammonia is very
toxic, even at low levels. It is broken down into nitrite
by Nitrosomonas bacteria.
Anaerobic
- An organism, such as bacterium, that can live in the absence
of atmospheric oxygen.
Bacteria
- Single-celled organisms, free-living or parasitic, that
break down the wastes and bodies of dead organisms, making
their components available for reuse by other organisms.
Back
Flush - The process of draining and purging impurities
out of a plumbing/filtration system.
Biological
Filter - Any unit designed to consume nutrients and particulates
from a body of water through the use of biological bacteria
and filtration media.
Buffer
- An ionic compound that resists change in its pH
De-chlorinator
- A chemical that neutralizes the presence of chlorine and
chloramines in city tap water.
Ecosystem
- A dynamic complex of plant, animal and micro-organism communities
and their non-living environment interacting as a functional
unit.
Enzymes
- Molecular proteins found in nature, which can catalyze (speed
up) chemical reactions.
Filter
Media - Any material with a tremendous amount of surface
area, used to colonize beneficial bacteria for water filtration.
Filtration
- The act or process of filtering. The mechanical separation
of a liquid from the solid particles floating in it.
Flocculate
- To convert into floccules or flocculent aggregates; to make
granular or crumbly; as flocculation of a pond causes organic
particles to clump together into larger clumps that can be
filtered, or will sink.
Macronutrients
- An element such as carbon, hydrogen, oxygen, or nitrogen,
required in large proportion for the normal growth and development
of a plant.
Micronutrients
- A substance, such as a vitamin or mineral, that is essential
in minute amounts for the proper growth and metabolism of
a living organism.
Microorganisms
- An organism of microscopic or submicroscopic size, especially
a bacterium or protozoan.
Nitrate
- (NO3 ) is a by-product of the breakdown of fish wastes by
beneficial bacteria living in the filter. Nitrate is less
toxic than ammonia and nitrite but can cause stress in fish.
Nitrate is nutrient for plants and unfortunately a nutrient
for algae.
Nitrite
- (NO2) is a toxic nitrogenous (nitrogen containing) pollutant
derived from ammonia by Nitrosomonas bacteria. It is toxic
at low levels to most fishes and is a common reason for losses.
Calcium chloride and sodium chloride have been shown to reduce
its toxicity. Nitrobacteria convert nitrite to nitrate.
Nitrification
- The biological or chemical transformation of ammonium nitrogen
to nitrate nitrogen.
Nitrogen
- One of the major nutrients required for the growth of aquatic
plants, usually present in water as organic nitrogen or as
inorganic ammonia and nitrate. High concentrations of nitrogen
can cause overabundant aquatic plant and algal growth.
Nitrogen
Cycle - The biological cycle in which toxins are broken
down into less harmful products by Aerobic bacteria.
Parasite
- An organism that grows, feeds and is sheltered on or in
a different organism while contributing nothing to the survival
of its host.
pH
- (potential of Hydrogen) A relative measure of the acidity
of a solution using a scale of 1-14. It is used to indicate
whether a solution is acidic (below 7), neutral (7) or alkaline
(above 7).
Skimmer
- A mechanical pre-filter designed to remove surface debris
and house the submersible pump.
Sludge
- Broken down organic debris accumulated on the pond floor.
(i.e., fish waste, dead lily leaves and tree foliage)
Ultraviolet
Sterilizer - A device that uses the process of radiation
to destroy organic compounds that pass through its ultraviolet
light.
