What does algae need to survive?
Algae only require a few essentials to grow: water, sunlight, carbon, and nutrients like nitrogen and phosphorus. From salt water to fresh water and everything in between, the diversity of algae means that there are suitable strains that can take advantage of nearly any water resource.
What are benefits of algae?
In the United States and other parts of the world, it is common to find algae in dietary supplements that help boost the immune system, repair nerve tissue, normalize blood sugar and provide the body with additional protein and fiber.
