My pound is a little one so this quantitie was a bit to much , i supposed to put only half of it. Anyways the pound color was dark bleu, I like it but i will search for a lighter Bleu color as this one it too bleu for my taste . Everyone single neighbor was amazed by the color of it and impressed in the same time.

Makes the pond a beautiful blue color.

Works well in my 1 acre rainwater collection pond. Nice color lasts for months or until a heavy rain pushes the blue water over the overflow. I prefer the blue color to the natures brown/green. Adding color to several spots along the shoreline is all you do. Color automatically spreads throughout pond.

Powerful, don't spill a drop on you or your clothes... as you try and wash it off you will see it goes a longggggg way. NO problems for pups, or fish.
