Application Rates

The Coptrol application rate depends on the degree of algae infestation, the kinds of algae present & the depth of water to be treated.

For Tanks & Troughs: 
Apply 2-5 mL Coptrol per 1,000 litres of water to be treated.

For Dams, Ponds and Water Impoundments, including potable water storages: 
Apply 4.2-8.4 litres of Coptrol per 1,000 square meters of water surface area at an average water depth of 1 meter or greater, or 5-10 litres of Coptrol per 1 megalitre of water.

*Use this calculation tool as a guide to calculate the amount of Coptrol to be used. However, please consult the label for directions.
