Using copper sulphate algicides
Copper sulphate-based swimming pool algicides can be used to:
control algae
improve water clarity
reduce the amount of chlorine- or bromine-based products needed
They do not:
control microorganisms like bacteria and viruses
eliminate the need for sanitizers
Copper sulphate-based products must be used along with chlorine- or bromine-based sanitizers to protect bathers.
The amount of copper sulphate-based algicide needed will vary depending on the size and type of your pool and its location, for example how much sunlight it receives.
Note:
Using copper sulphate-based algicides in swimming pools is not dangerous to swimmers. If you follow all label directions, copper sulphate algicides should not cause skin irritation. However when handling undiluted products, care must be taken to reduce the risk of skin irritation.
