HYDRA BLACK LIQUID DYE 250ml treats UpTo 1063 litres Concentrated Liquid Pond Dye Free of Pesticides, Algaecides Safe for pets fish plants

I used 2 small bottles last year in my largish pond. put it in as soon as it started to really warm up, and went the whole season without suffering from the usual plague of blanket weed. the man who looks after my pond's filtration system suggested it. It works! you can still see the fish, and everything looked great. Have purchased the large size this year because its more cost effective.

The media could not be loaded. Crystal clear water is always good to have in the garden pond but the downside is that the fish were easily seen and picked off by the heron.I opted for the black dye as this suggested a mirror finish and dark looking water. In addition, it can also reduce algae buildup as the light does not penetrate as much. Clear instructions are included based on how much water your pond holds.The results are superb. I highly recommend this product and the results are better than I had hoped for. A massive 5 star rating

Didn’t need to use much & seems to be lasting very well

Pond water looks lovely with this blue dye

The media could not be loaded. This was my first time using a pond dye, I'd always had natural ponds before but i wanted that glossy mirror reflection for my new wildlife and barrel ponds.You only need a small amount, i used 10 drops in each pond so the bottle should last well into next summer with regular top ups.As you can see it gives a lovely reflective appearance to the water and hides any bricks and plant pots inside the pond.I definitely recommend this if you have water in your garden.

Product is probley OK but it makes the water to dark; difficult to see the fish

I bought this liquid dye for my pond that is approx. 2400 litres, as it always kept getting green algae which was also bad for the fish. I added this about 3 weeks ago and no algae and the fish are loving the clear water.It also looks good with the sun reflecting off the water and the fountain and against the plants, also you only use a very small amount, so I have a few years supply with this 1Ltr bottle.

We have a largish pond with blanket weed, we use this dye and it works in so much as it makes the pond look good but it will not eliminate your blanket weed problem, we will be looking at adding another substance to deal with the blanket weed but will continue using the dye for the look it gives our pond.
