Chemical Application

Got a dirty ... Apply our products

As a short term environmentally friendly solution, applying chemicals can quickly breakdown the organic matter and contaminants in lakes, ponds, and wastewater lagoons.

The use of chemicals as a short term lake and pond management solution will enable you to implement longer term solutions like aeration & circulation

The use of aquatic registered herbicides and algaecides are an effective short term water management solution that relieve your water body from the congestion of aquatic plants and algae.

A good place to start is by identifying the type of plant or algae that is infesting your lake or pond. There are some very useful tools online that can make this easy.

The first has been developed by NSW government, called ‘Recognising water Weeds’ and another, developed by the Brisbane city council, that can be found here

Once identified... What's next?

Once the type of weeds have been identified, an appropriate aquatic registered herbicide or algaecide can be selected and applied.

The two most common aquatic registered herbicides are Reglone, wielding Diqaut as the active ingredient, and Eraze 510 with Glyphosate being the active ingredient.

As for algaecides, the two most common are Kupramine and Cupricide, housing components that kill both filamentous and planktonic algae.

Let’s dive a little deeper on CUPRICIDE. CUPRICIDE is a mixed copper alkanolamine complex. In this form, CUPRICIDE provides maximum algaecidal efficiency but has a low toxicity level, being non-harmful to fish. The organic complexing agents used in CUPRICIDE ensure that the key active ingredient (Copper), remains in the solution and does not precipitate out like some other copper algaecides, namely copper sulphate. Copper sulphate has been used extensively throughout Australia as an algaecide, but has several drawbacks associated with its use.

Firstly, copper sulphate is not algal specific – in fact, it can be quite toxic to other aquatic life when used at high concentrations.

Secondly, if the water contains a high concentration of carbonate ions, the copper ions will combine with the carbonate and form an insoluble precipitate of copper carbonate. This precipitate sinks to the bottom of the water body where it forms a toxic slime. This formation also renders the copper unavailable for the control of algae. To compensate, higher levels of copper sulphate are used, which as stated above, may seriously threaten other aquatic life.

Finally, sulphate containing algaecides also combine with hydrogen ions in an aqueous solution to form sulphuric acid, which is highly corrosive.

For these reasons CUPRICIDE is a much more cost effective and efficient product for algae control than copper sulphate.

Applications

Conducted via surface spraying techniques, designed to battle surface and emergent plants, and via sub surface dosing for submerged plants. In doing so, results can be seen in just 7-10 days after application.

Chemical application is often the first step in the water remediation process for lakes & ponds that need to be cleared of overgrown weeds and algae. In some cases chemical application is neccessary before Aeration & Circulation can be applied, and sometimes re-applied once these solutions are in place.

Clear & Healthy Looking Water Body Free from any algae or aquatic weed

Depending on the age of your water body and the type of algae or aquatic weeds in it you should expect great results within the first few weeks from applying the algaecides. After, when installing your mechanical circulation and aeration system, your lake and pond should maintain in great shape.

Scope: Install Solar Powered Circulators to assist storm water basin management.

Bioremedy were engaged to provide Solar powered water circulators to assist with lake destratification in the western districts of Brisbane, QLD. As part of the ongoing management of these lakes, chemical and biological application programs take place each month to assist with the control of unwanted algae and aquatic weeds.
