Hydra lake shade hides unsightly accumulations of garbage and debris at the bottom of the lakes. The product also protects aquatic life from predators by hiding them under the coloured water. The natural shadow effect in the dyed water is visually appealing to the onlookers. Beautiful colour infused in the water through Hydra Lake Shade boosts the reflective properties of the water bodies, by giving them a vibrant, natural look and creating a spectacular background for aquatic water plants.

The product is safe to use in lakes with fish and other aquatic life, including plants. Domestic or wild animals may drink water from the dyed lake without any harmful effects.

Hydra Lake Shade is a food-based pond colourant used by Fishing Clubs, Fish Breeders, Golf Clubs and local authorities.


Dyes can be used for bird/pest control and to make the water seem deeper than it is.


Dilution Rates:

  • 1 kilo treats up to 4 million litres of water (approx. 1 acre at a depth of 1 metre).
  • Packed in water-soluble sachets 
  • Retreat approximately every 3 months.

Simply throw into the water where Hydra Lake Shade dissolves on its own without hard-to-dissolve clumps left behind. Retreat the water body after 3 months to maintain the colour. Dilution rate may vary depending upon the intensity of the colour required and original colour of the water body

Can I use this dye if I have fish in my pond?

Yes. Hydra Liquid dye is food grade dye, and it is completely safe for fish, plants and invertebrates.

My dog sometimes drink water from my pond. Will it be okay?

Yes, absolutely. Dogs, cats, birds, wildlife - this food grade based dye is safe to be used for drink.

Although, if your dog often drinks pond water - be aware of Blue Green Algae https://www.bluecross.org.uk/pet-advice/blue-green-algae-and-its-dangers-dogs

What happens if we put too much pond dye in our water?

The water will be a deeper shade, and possibly opaque. Over time, rainfall will dilute the colour to the point where it will all be gone. You can also add more water, or partially change water to dilute dye. If emptying the pond is required, the water should be flushed into soil beds – please avoid letting over dyed water get into surface drains or streams. Any water getting into a stream or drain will not be harmful, but it might concern other people if they see odd colour in flowing water - they might report it to authorities as ''pollution''. 

Can water dye leave stains?

Yes, but nothing that can't be washed. It will most likely stain your hands and clothes - that's why it is recommended to wear gloves and protective clothes when using our product. Also, when diluted - it might stain the rock or surface where the water touches, but it is nothing permanent - sunlight will fade any residue.

Can we use more than recommended?

Absolutely! Our recommendation is top maximum that our dye can work and still be visible. Please wait 24 hours before adding more solution to the water, as sometimes it takes time for colour to 'settle in''. However, if you are using more than it is recommended - you can expect colour to be darker, more vibrant and water can seem deeper.

In case you overdo it, nothing to worry about. It will fade out with either rainfall or sunlight, or you can dilute water with adding more water or partially changing water.
