One of the most attractive features of a tropical fish tank in the home is the potential it has for creating a beautiful underwater garden with a variety of exotic plants. The visual benefits are obvious but there are also important unseen advantages too!

The simple function is the way carbon dioxide is absorbed and oxygen is produced by the plants. As the fish are consuming oxygen and producing carbon dioxide, they benefit from the process, as do the plants! However, there are more subtle and less obvious processes also aiding the water chemistry by the growing plants.
