Aquatic Blue™ – Colours & Blocks UV - where to use it
  • What are the benefits of using Aquatic Blue water dye?

    Aquatic Blue is a professional water dye that offers a multitude of benefits. Experience the desired blue aesthetic while reducing UV light and improving water quality. By limiting light availability in the water column, the reflected sunlight from the blue colour may also help maintain lower water temperatures, which in turn promotes higher oxygen levels beneficial for fish health and the growth of essential bacteria.

  • Is Aquatic Blue harmful to fish and other wildlife?

    Rest assured, Aquatic Blue is completely safe for fish, frogs, wildlife, humans, pets, and livestock. It has been carefully formulated to ensure harmlessness while providing optimal results. You can swim and enjoy your water body without any concerns.

    Absolutely! Aquatic Blue is not only safe but also incredibly easy to use. It poses no harm to fish, frogs, livestock, pets, or humans. With Aquatic Blue, you can confidently enhance the aesthetic appeal and water quality of your water body.

  • Why do people dye ponds and lakes?

    The reasons for dyeing ponds and lakes are manifold. By using Aquatic Blue, you can enhance the visual appeal of your water body while reducing UV light penetration through the water column. The result is not only a visually pleasing pond or lake but also improved water quality that can support the health and longevity of aquatic life.

  • Will Aquatic Blue dye stain rocks?

    No, Aquatic Blue is a safe and user-friendly dye. When fully diluted, it will not stain rocks, pets, livestock, or anyone swimming in the water. Enjoy the benefits of Aquatic Blue without worrying about unwanted stains or discoloration.

  • Will Aquatic Blue stain Sandstone, machinery or water features?

    No, when fully diluted, Aquatic Blue will not stain sandstone, machinery or any other water features you may have.

Aquatic Blue

It made a real difference to the visual look of the pool. It has slowed the algae a little. It is very concentrated so not much is needed and it is lasting really well.

Love it! Went from **** brown dam to sparkling aqua! I probably used too much at once so next time I'll do add a smaller amount at a time

Aquatic Blue 500ml

Product arrived quickly. I was little dubious as to the quoted dilution ratio however it turns out to be correct as the product concentration is incredible. Great long lasting product.

Does a great job.

Second order for our 13,000 litre pond. Makes a big difference. Wish they made a black one though.

Coptrol treatment will vary depending on the severity of your algae bloom. For severe algae blooms use the lower volume or surface area to calculate how much Coptrol needed.

Coptrol™

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.
