Coptrolâ„¢

For the safe control of all types of algae in all types of water bodies.
coptrol-15l-and-1l-png

How it works

Algae actively seek out and absorb Coptrol for its nutritional value. Once absorbed through their cell wall digestive enzymes within the algae cell breaks down the copper chelate and releases the active constituent inside the algae cell to kill it. Coptrol is solely used for the control of algae and does not control aquatic plants.

Method of application

Once diluted, Coptrol can be applied directly from a bucket, watering can, knapsack sprayer, horticulture sprayer, firefighter pump sprayed from the bank, or from boats or aircrafts.

Alternatively Coptrol can be dripped directly into flowing water in high volume treatments such as flood irrigation water.

How much do you need?

The product and amount required will depend on the size and type of body of water being treated. Use the calculator below to work out exactly how much you need.

Works really well!

Followed the instructions and put in 5ml on the first treatment, and the algae reduced tremendously. Since then we put in 2.5mls the second week and another 2.5mls the 3rd week. The pond is the best we have ever seen it, you can see the bottom of the pond and the water is very clear with no elgae. there has been no effect on the fish whatsoever... the best product we have found!

Works quickly but kills tadpoles

Sploshed 500ml in yesterday in line with the directions and volume of water. The algae is dying and the water looks a bit clearer. However, the tadpoles are floating - dead. I assumed, wrongly it seems, that all aquatic life would be safe but alas not. Bit sad about the taddies.
