Algae Free is formulated with non-acidic ingredients making it safe for use around plant and animal life. Not only is it safe to use, but it is also concentrated too which makes light of tough work. It is also 100% biodegradable and phosphate free. Algae, which is considered a simple form of seaweed, can grow on virtually any surface that's exposed to water and/or humidity. Unlike most plants, algae lacks leaves, roots, and stalks, which allows algae to take up residence on virtually any surface. What's more, algae is very fast growing and it can arise and grow to a point where it's visible to the naked eye in a matter of hours.
