Hydra Fluorescent Green liquid dye provides an impressive reflection and colour to your pond and/or water feature and has been used by the likes of landscape gardeners, garden pond/water feature keepers, local authorities, golf courses, and farm ponds.
With its quick dispersion quality and high concentration, its usage, even in low quantity, is enough to enhance the aesthetic appeal of your pond or water feature. It safely protects and shades your pond or water feature in a fluorescent green colour.
Hydra Liquid Dyes are environmentally friendly and non-toxic, meaning they will not harm birds, reptiles, mammals, or fish. So, if you have fish with your pond, adding dye to your pond will not affect them or their health, if anything, the dye will help to protect them. Dye used within ponds with wildlife within will help deter predators, for example, fish will be protected from the predators such as herons.
Water from ponds and water features that have been dyed with any Hydra Liquid Dye, is safe to use as part of irrigation of crops, meaning, if you wanted to change the water in your water feature, for example, you can empty it onto your flowerbeds and they will not be affected.
Liquid dyes all work in the same way as food colouring; It dyes something in your required colour. However, liquid dyes used within ponds and water features offer an additional benefit in that they can help reduce plant and algae growth. Dyes do not, however, hinder the growth of all aquatic plants, they are recommended for submerged plants such as pondweeds, watermilfoil, and elodea, as well as plants such as water lilies.
*Please note that all images are for illustrative purposes only, Actual colour may vary depending on pond water conditions.
Administering dye to your pond or water feature is as simple as pouring the correct measurement needed of dye into the water. It will quickly disperse within and around the pond and/or water feature, meaning no need to spray of spread the application our yourself.
Water dyes can be applied to ponds and water features of any size, small or large.
Not only can water dyes be added to ponds and water features, they have also been known to be used in small amounts, to glass vases and centrepieces at events and weddings to create drama and aesthetically appealing looks.

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

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
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''.
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.
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.
My uni project was an art installation with the theme to represent pollution in water and raise awareness. The colour was so bright and just right for this purpose. Super happy.

We run a zombie apocalypse escape room event. We needed to use a couple of dyes to represent a toxic waste leak. I found the yellow which I purchased and I found this Fluorescent green which looked fantastic and looked completely real with the theme. I am super happy with both colours and a plus is you only needed a small amount so I can reuse for future events. 5 stars.
Arrived in good time and nice colour.
Quick delivery and great colour.
