Hydra quarry water dye is a simple and cost effective method to keep the people from harming themselves in abandoned quarries. The quarry water may be seemingly harmless but often lead to damaging, and sometimes even fatal consequences to the unaware swimmers. Flooded quarry waters are often contaminated and there may be non-visible machinery left behind. Skin rashes and upset stomach are some common problem reported after swimming in quarry water. Sometimes swimmers hit upon hidden machinery and harm themselves.

Hydra Quarry Lake Shade alters the colour of the water and the water is no longer appealing for swimming purposes. People often break fences and do not pay heed to warning signs, but Hydra Quarry Lake Shade act as a natural deterrent to the people and keeps them away from using quarry waters for recreational purposes.


The product, applied in quantity, as small as, 100 grams could treat up to 100,000 litres of water and one kilogram would colour up to 4 million litres, approximately one acre (4000 sq. m) of water surface with a depth of 1 meter.

Easy to use water soluble powder, packed in self dissolving bags. Simply toss into the water to be treated, natural wind driven currents will mix the product over a day or two into the whole water body.

A very simple yet cost effective way to keep people from coming to harm in dangerous disused quarries and other water bodies. Fences costing tens of thousands of pounds might not stop them from entering the water but Hydra Quarry Lake Shade will for the cost of a few hundred pounds.

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.
