Why is my garden fountain green? Algae is a plant that can be as small as microscopic, all the way up to what is commonly known as seaweed. Aside from size, it can also look pretty different. It is usually either green, brown, or red. It is also very adaptive to it’s environment.
The growth and accumulation of algae can be aggravating, hindering your enjoyment of your garden fountain while also potentially clogging the fountain’s filtration system. Regular maintenance of your fountain can help prevent algae growth.
