Review: Excellent product and you need very little. - We have a shallow corten steel water feature that suffered with algae because the water got too warm to support plants. This water dye has been in for two weeks and so far seems to have stopped the algae growing. I only needed 7.5ml (three teaspoons full) to make the water black (actually dark purple). The undiluted dye did stain my fingers so beware.
Review: Great product! - This product not only deflects the suns rays , preventing the formation of algae, Not only makes the water look beautiful, I chose black which sets off the white water lilies I have, but most importantly for me, is harmless to plant and wildlife. I’ve bought in the past, and will continue to do so. First class .

## Features

- Environmentally Friendly: The Hydra Liquid Black Dye is a pond dye water treatment that works in all ponds and water features either small or big. It is a water dye that is environment-friendly and non-toxic for fish, birds or other animals.
- Economical: Hydra Liquid dye is food grade dye that is very economical to use. It acts as a pond dye that is also an algicide. It will reduce the sunlight penetration and eventually will reduce the growth of algae because it slows the effect of photosynthesis
- Mirror finish: Hydra Liquid Black Dye gives a mirror finish to your pond anyhow, the water will be a deeper shade, and possibly opaque if extra liquid is added. 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 the dye.
- How to use: 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 or spread the application yourself
- Customer satisfaction: In case of any query related to Hydra Liquid Black Dye, feel free to contact us. We will be at your service and try to provide an answer as soon as possible.
