1 Gallon 4X Blue Pond Dye - Treats Like 4 Gallons & Covers 4 Acres, Concentrated Pond Dye Blue, Liquid Pond Shade & Blue Dye for Ponds and Lakes, Provides Natural Blue Color, Safe for Fish & Wildlife

Works exactly as advertised and lasts good amount of time. My pond is only 175 square foot but is a depth of 3.5 feet. Just a cap full of this product colored my water perfectly for a couple of months!

Second yr using this and love it. Very easy to use just pour in at my fountain and tbe color is almost instant. Havent had any problems with water for the cows as well

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.

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.

This is my second purchase of this particular brand of pond dye. It is concentrated and therefore treats as well as a full gallon of most other brands! The price seems to have risen on most ALL of these pond dyes, so I found this one to be a bit of a bargain! Works great, easy to apply (just wear protective gloves when applying)! Also, disperses evenly in a very short while (TIP: Always try to apply upwind!). Great results and pleasant color. Color can be adjusted somewhat by the amount of dye used, therefore, start off with a smaller dose and add more for a deeper color!

Wanted to slow the growth of Duck Weed and I think it helped but it will take more than the blueing of the water to rid the pond of it. I’ll order again to get the pond darker next summer. It does stain skin and clothes or anything that comes into contact with the spray or lid

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

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.
