Hydra Black Water Dye creates an amazing reflective mirror finish in the water body, greatly improving the visual appeal of the landscape. Ideal for use in reflection or infinity pools due to its mirror effect producing quality.
Pond weeds, like all plants, algae and many bacteria, use the energy from sunlight to convert carbon dioxide into organic compounds, most typically, sugars. Without sunlight, photosynthesis could not occur and life as we know it could not flourish. Because they can synthesize food directly from carbon dioxide using light energy, pond weeds are classified as photoautotrophs. Most appear green in colour due to the light-collecting pigment known as chlorophyll-a.
Hydra Black Powder Dye is very effective in prohibiting all types of pond weeds and algae’s. By using a non-toxic colorant in the water, you can partially filter sunlight, thereby thwarting the photosynthetic process for many aquatic weeds and algae.

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.
