Does give my boring fountain a tint of blue. I can have it as dark or as light as I wish.

This blue pond dye cleared up our cloudy-looking pond and made it very blue. This product works wonderfully.

It’s a good sized bottle, so you won’t have to keep buying tiny bottles of food coloring anymore, and it’s safe for birds! One word of caution: less is more! Use a little at a time, before finding the shade you like.

Works as expected, 350 gallon uses about 8ml for nice aqua blue color. Not sure yet how long coloring will last but we will see?
