Hooking up a GFRC boulder fountain is easy. GFRC has the look, feel and texture of a real rock. It is made of a mold from a real rock. I sold real rocks before I found GFRC, and when I started bringing in the GFRC rocks no one wanted the real ones any more. I still sell a real one once in a while but my customers overwhelmingly choose the GFRC boulder fountains.
