When Black Beard Algae first appeared in my tank, I had no idea of the destruction it would cause. It's brutal algae!
For many years my tank was under a window, so I never had need of a light as the plants got everything they needed from the sun. With lots of plants, the aquarium had a nice little eco system going, I never had any problems with algae as the bristle nose catfish constantly cleaned the tank for me.
