How to Use Coptrol in Farm Dams

and Ponds

Farm dams and ponds very often develop algal problems. They can range from physical inconvenience such as blocking of screens and filters, pumps and irrigation equipment to stock losses from toxicity caused by accumulation of blue green algae. The problems are aggravated where water is enriched by nutrient run-off, so heavily fertilized areas are a particulary good source of algal nutrients.

In drought seasons where water levels are low, algae

may be a major problem also.

If algae is a problem in your dam or pond follow this 5 step method to keep your waters clear and bright.

1. First identify the algae present. If you are not certain visit

www.algae.info. 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

at our general recommendations.
