How to control algae in Ornamental
Ponds and Fountains
Shallow ponds ideal for growing algae
Because ponds are generally shallow with significant surface area
are a fertile breeding ground for algae, particularly in the
There are hundreds of different algae that can cause a problem
most of them unsightly, and most causing problems
including the blocking
Frequently fish are added to the pond and they too assist the
growth of algae.
Fish faeces are an excellent source of nutrient
for algae. Often fish are over fed
and the excess feed falls to
the bottom and as it rots is another source of nutrient.
sources of nutrient are fallen leaves or fertilizer.
This excess of nutrient leads to algal blooms which in turn take
out of the water and leads to fish suffocation
from lack of oxygen.
will rid the pond of algae but before applying it there
important safety issues to check if fish are present.
• The water temperature of the pond must be 16C (61 F) or more
• The calcium carbonate of the water must be 50 PPM (50mg/litre)
• The water must be aerated
• You should read and heed

• Dead and decomposing algae will use the dissolved oxygen in
So where fish are present, and there is inadequate
t is recommended that a
third of the pond be
treated at a time, at intervals of at least 7
days, to allow the

Coptrol is specific to algae and will not affect the plants in
If algae is a problem in your
ornamental pond or fountain
follow this 5 step method to keep your waters clear and bright.
First identify the algae present. If you are not certain visit
. This site enables you to identify all the
algae in Australia.
Now calculate the volume of water to treat. Ignore depths

How to calculate the volume of water to
Next calculate the amount of Coptrol needed. An easy way
to calculate is:
• If the algae is fine and free floating use 2 mL of Coptrol
per 1000 Litres (1 cubic metre) of water. That is equivalent
to 2 Litres of Coptrol per 1000 square metres of
• If the algae is long and stringy use 5 mL per 1000 litres of
water (1 cubic metre) or 5 Litres per 1000 square metres of
Dilute the required amount of Coptrol using a 1:10 or even a
Coptrol water dilution.
The best application method is by spraying. Apply on a sunlit
wind free day when algae first appear. If this is impractical
