AquaDesign Blue Liquid Pond Dye 1000ML For Ponds And Water Features TREATS 40,000L

Seems to be working well to make the water look great

WARNING:There is no secondary seal under the cap. You have to break an outer seal to take the cap off. As I did that, blue dye squirted out over my beige trousers and my sandstone patio. Doh!BEFORE:The water was starting to go murky green. You could only see about 6" into the water but it sparkled nicely over my series of waterfalls.AFTER:My picture was taken reflecting a solid grey sky.The water quickly became a uniform very dark blue; almost navy blue. I much prefer that to the bright blue advert images. It looks quite natural, rather like dark water reflecting a blue sky BUT the water does not sparkle anything like as much. On balance it is better than the previous murky green with sparkles.CLEANING UP:1. The dye came off the patio with a thorough hosing but I gave up on the trousers.2. My wife came to my rescue. She soaked my stained trousers in 'Vanish' but no matter how much 'Vanish' was used and how much rubbing was done, it still looked as if a pen had leaked in my pocket. She soaked the trousers over-night and amazingly, the dye has 99% gone.There's a moral in that story somewhere. I'm sure she'll tell me what it is.

That you are always on time and very good productsAlways pleased thank you Amazon

after fighting a loosing battle with pond weed and green water in my fish pond for almost three years getting bigger uv lights and bigger filters, I met a bloke who was a grounds ma at a large country park and I don't know how we got round to talking about fish ponds but we di, I mentioned my troubles with the water and he said they put this in their lake and their lake is huge I've waled round it and it took over two hours. so I bought some followed the instructions and my water is now so clear I can count my fish and see the bottom of the pond its about three feet deep

Makes the water look very good. Unfortunately it hasn't stopped the blanket weed.

Good product and service

Add this to your pond and you won't get any algae, your water will have a blue colour to it but it looks good , it doesn't harm the fish or plants

I had problems calculating the correct doseage, and put in a little too much. I had to drain 75% of he pond and refill with fresh clean water to get the correct colouration. There was no pipette to measure the dye.
