What is Coptrol?|coptrol algicide|coptrol algaecide 

It is a new generation algicide researched by Rural Chemical Industries (Aust.) Pty Ltd. Coptrol is a water-soluble chelated copper compound in which the copper is held so tightly it cannot be "stolen" by contact with other substances. It uses special organic chelating agents resulting in a uniquely effective algicidal action. It offers a new approach in the control of free-floating and filamentous algae in aquatic environments.  

Where can it be used?|where used

Coptrol algaecide is specifically designed for safe and effective use in rural industry and for human and livestock drinking water supplies. It works in all kinds of water, hard or soft, salt or fresh, turbid or clear.It will clear up existing algae and prevent future growth, keeping water clear and bright.

Why is it a better choice than copper sulphate?

Because it overcomes the environmental problems posed by copper sulphate products. The chelated copper used in Coptrol, as a “natural” compound, is low in toxicity to fish; however, it is still highly effective at controlling algae.
 ​
Coptrol is efficient and effective and an environmental safe option.
​
Is it effected by hard water?

Coptrol eliminates the problem of “hard” water. 
 
Coptrol permits lower concentrations of copper to be used in algae control. 
 
Because Coptrol  does not precipitate in hard water the application rates are less critical. 
 
Coptrol achieves longer copper persistence in water at levels that are toxic to algae.  
 
Coptrol is less toxic. 

Use of Coptrol in aquatic environments has been a more  efficient and effective means of control over algae than copper sulphate.

Algae are a diverse group of simple, plant like organisms. The algae in freshwater do not generally present problems. Indeed, algae are the most important photosynthesizing organisms on Earth. They capture more of the sun's energy and produce more oxygen than all plants combined. 

What problems do algae cause?

Excessive growth of algae can reduce the aesthetic and recreational value of a water body, can trap litter and sediment, and reduce the holding capacity of a dam and cause smells and scum when decaying. Algal blooms may deplete oxygen concentrations in water which can smother fish, other animals and plant life, Floating algal masses can smother rice crops and prevent young plants from emerging, They block pipes, siphon tubes, irrigation channels and pumps severely impeding water flow. Certain blue-green algal blooms are toxic and cause a rash known as swimmer's itch, while powerful neuromuscular toxins released by other cyanobacteria can kill fish living in the water or the animals that drink the water. In certain conditions, cyanobacteria may form dense blooms, which may produce toxins that make seafood poisonous to humans. Even if the cyanobacteria do not produce toxins, blooms can cause water to have an unpleasant taste and odour.

Coptrol is manufactured in Australia, where testing and development is a continuous process.

Coptrol will not control aquatic weed.  Common weeds often mistaken for algae are Duckweed, Azolla and Salvinia.
