Aquatic Blue

Transform your water body

Pond Dye for all Bodies of Water

Aquatic Blue by Aquatic Technologies does more than just colour your water
  • Reduces UV light penetration through the water column
  • Keeps algae under control [1]
  • Impairs aquatic plant growth without increasing turbidity [2]
  • Can achieve control of rooted aquatic plants [3]
  • In a non-herbicidal alternative [4]
  • Decreases overall water temperature which increases oxygen saturation [5]

Aquatic Blue Pond Dye Benefits

Dyes any water

Aquatic Blue and Aquatic Blue Eco are able to dye any type of water including: brown, turbid, murky, cloudy, and tannin.

clear water with barley straw
Blocks Sunlight

Without light, some aquatic weeds and algae are not able to photosynthesise and grow[6] [7] . Thus the reduction of light hinders aquatic weeds and algal growth[8] .


Aquatic Blue and Aquatic Blue Eco will not harm any of the critters that live in the water or use the water.

Aquatic Blue is Safe

Aquatic Blue is safe to use in the presence of humans, livestock, fish, domestic pets and wildlife. Once diluted into the water column it is safe for irrigation and swimming and the dye will not stain skin, hair, clothes, plants, rocks or sand.

Aquatic Blue is backed by Science

This science-backed product works by restricting the penetration of UV rays into the water column. Without light, some aquatic weeds and algae are not able to photosynthesise and grow[6] [7] . Aquatic Blue filters the sun’s rays, reducing the amount of UV light present in the water body. The reduction of light hinders aquatic weeds and algal growth[8] . Aquatic Blue gives your body of water a gorgeous blue hue.

Because of its light-filtering properties, Aquatic Blue may decrease water temperatures[5] where applied. This can be beneficial for increased oxygen saturation, which in turn can keep fish healthy for longer[5] and support the growth of the ‘good’ types of bacteria in your water.

Because Aquatic Blue changes the colour of the water, this may prevent fish from being predated as they can be harder to see due to the refraction of light against the blue[5] .

Basically, aquatic plants and algae need sunlight and nutrients to grow[1] for photosynthesis Aquatic Blue prohibits the penetration of light into the body of water. Limiting the light reduces the ability of plants and algae to grow. The science is quite simple: this aquatic dye is formulated to ‘screen out’ red-orange and blue-violet light rays from the sun. As the dye reflects sunlight, water temperatures remain lower. Less light means algae growth may be suppressed[9] [10] .

  • Easy to apply
  • Non toxic and environmentally friendly
  • Safe for fish, plants, animals and humans alike
