The Safety of Decorative Fountain Algae Control02/08/2021Decorative Fountain Algae Control is an EPA registered and regulated product that is similar to other types of algaecides. The label often brings about the question: is it safe for wildlife? The label states that the product is hazardous to humans and domestic animals, though it is not in the way that you might think. Doing something like drinking the product straight from the bottle would be harmful, so therefore we are required to place this warning on the label. Using this product appropriately and responsibly will not bring harm to you or wildlife such as birds who may drink out of your fountain. Decorative Fountain Algae Control is strictly meant for fountains. Use product lines like Koi Worx or Crystal Blue for treating ponds or lakes. We would not recommend using Decorative Fountain Algae Control in bodies of water that contain fish, especially those with koi, goldfish, or grass carp. These types of fish are sensitive to copper sulfate, which is the active ingredient in this product.
