This is a great medium, it is cheap and lightweight and amazingly effective. Perlite is a naturally occurring volcanic rock that is treated in a furnace in a process known as exfoliation.
Perlite is highly recommended because it has superb capillarity. Capillarity is the ability to lift moisture from reservoir and it is the key to the success with Perlite. Perlite does have a tendency to attract Algae which will appear as a green stain on the surface, this is nothing to worry about.
