4X Blue Pond Dye - Transforms Murky Water to Natural Blue - Super Concentrated Lake & Pond Dye - Liquid Shade Treats Up to 1 Acre - Safe for Fish & Wildlife (32 oz)

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.

very good its work well

Added one bottle to our 3 acre lake and it was a beautiful blue color. Awesome product for the price

looks very nice, does reduce algal growth and not harm fish, said to last a year, mine lasted longer but turned greenish blue

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.

Small pond owners beware start with just a cap this stuff is made for a giant pond like in a neighborhood

I won't purchase this product again. The dye is not 4X concentrated as before.

This pond dye goes along way. One jug will do quite a bit. I used half of one on our small farm pond. It looked beautiful.

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.
