Good value, works well.
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!

Great way to color pond water
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.

4X Blue Pond Dye - Transforms Murky Water to Natural Blue - Super Concentrated
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!

a drop is sometimes all you need
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.
