Negative Positive
Title: Lake Dye
Review: Crystal Blue Lake and Pond Dye was purchased to keep moss from growing in my lake. It turned the water blue for about 3 weeks and was pretty, but it faded away. It didn't stop the moss from growing. If you don't mind pouring it in your lake pretty often, it really makes the water a pretty blue. I bought some Curtine-plus to stop the moss and it worked, but doesn't turn the water blue like Crystal Blue does. I just wish it would last longer.
