Control Algae in Drinking Water
Can Coptrol be used in drinking water?
is highly effective and proven method of eliminating blue green
algae in potable water supplies.
Is it approved?
is approved by the APVMA
(Australian Pesticides and Veterinary Medicines Authority) for application
in potable water (water suitable for drinking) reg no. 31030 and can be
sprayed, dripped or flown onto waterways to treat blue green algae.
What species of algae are most important?
The most important group of algae affecting potable water supplies
are those described as blue greens.
There are a number of species of
blue green algae
and many of them
produce highly toxic compounds that directly target either the liver or
central nervous system. In their purified form these toxins are more
potent than either arsenic or cynanide.
When a potable water storage system is contaminated by blue green algae it is important to minimise algal cell growth as algae cell population is directly linked to toxic
concentration. Large blooms invariably lead to higher levels
of toxin in the water.
We recommend early treatment as this strategy ensures large numbers
of toxin producing blue green algal cells can be prevented from developing
into a bloom, it also ensures the most cost effective use of
If algae is a problem in your drinking water supply follow this 5 step method to keep your waters clear and bright.
1. First identify the algae present. If you are not certain visit
. This site enables you to identify all the common
algae in Australia.
2. Now calculate the volume of water to treat. Ignore depths below
1 metre. We have a page which explains the methods used to
determine the amount of water to
treat. If you need assistance
see How to
calculate the volume of water to treat with Coptrol.
3. 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 surface area
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 surface area.
4. Dilute the required amount of Coptrol using a 1:10 or even a 1:20
Coptrol water dilution.
5. The best application method is by spraying. Apply on a sunlit
wind free day when algae first appear. If this is impractical look
