Filamentous algae can develop in livestock watering troughs during summer restricting livestock from access to the water. Most troughs in Australia are usually fed from either a main concrete tank or a turkey nest. For best results dose the header tank or turkey nest at the rate of 5 mL of Coptrol per 1000 Litres of water.

For example 20000 L tank will require 100 mL of Coptrol (20 x5). 

The most practical way to apply Coptrol in this situation is to mix

the required amount of Coptrol in either a watering can or bucket, fill the

can or bucket with water and then disperse the mixture evenly over the

surface of the tank or nest. Coptrol is perfectly safe in the drinking water

and will not affect livestock.  Remember it takes about 48 hours for Coptrol

to take effect in the trough and if animals are regularly using the trough

Coptrol has little chance to work as the treated water is consumed before

Coptrol can start acting. So if possible restrict access to the trough or portion

of the trough till the algae are removed.
