Hydra Blue Liquid Dye

I use it for my pond of about 1000 liters &very small amount is enough!
Be careful not to overdo it because the effect is really strong!
I ventured with a drop in a tub in a tub and I had to change the water 😅
Dosed with a syringe it is perfect!

This product will help eliminate blanket weed and will give the pond a lovely blue tinge. It has good clear instructions and doesn’t harm the fish or plants. Excellent products.

I have a fountain and am very happy with the effect given especially at night when the fountain is lit up. Plus it doesn't stain the stone will order again.

Gives a fantastic shimmering effect to my pond water, very strong so only add a few drops at a time you can always add more if required, seems to last a long time in the water.

Has transformed the look of my pond. Make sure you wear plastic gloves when using.

I have used water dyes from other companies in the past, so based on that experience I bought a 500ml bottle. This Hydra blue liquid dye is definitely much stronger, it will properly last me a lifetime. Gave a spectacular colour, colour shades change depending on how much you add. I would highly recommend this product to anyone that is look for a blue dye for their pond or water feature.

Very strong product, you only need a tiny amount, gives a great blue in the water showing off my aquatic plants in the shallows.

Hydra blue liquid dye has given my pond a great blue colour. It's doing its job very effectively preventing the algae from growing and blocking my pump.

Has 100% stopped the algae from forming in my pond, fish seem to be less anxious as predators can't see them as easily. This product is very strong so add it very gradually, it is easy to overdo it. With each addition, allow at least 20 minutes for the pump to circulate the dye throughout the pond before adding anymore.

My pond is directly in sunlight most of the day so with this product it has really cleared up my pond. The pond looks very impressive and still looks great but I will very be trying out the black liquid dye next time.
