Blue Lake and Pond Dye - One Gallon of Professional Lake & Pond Dye - Treats Up to 1 Acre - Royal Blue Color - Safe for Fish, Wildlife, Pets & Children

Good dye

Works well!

Easy in stall

I used this for a small fountain and used just a little bit. The color is pretty dark blue and makes it look unnatural. In a pond with thousands of gallons of water it might be ok as it gets diluted enough. I was hoping for something that is more emerald to bluish and not this very dark blue. I will see how it looks when it's more diluted when I add more water but next time I will look for some emerald color. Also make sure you use gloves as it will really stain your hands. It goes away within a day. It did stain my water fountain, though. I didn't try to clean it yet so I am not sure how permanent it is. But the blue stain doesn't look nice when you approach the fountain. I still give it 4 stars because I might just have used too much for our small fountain.

Great product

Works grate easy to use

Great product

This product gives my one acre pond a beautiful blue hue and at the same time helps in controlling the aquatic weed growth by limiting the amount of sunlight penetration. Great value.
