In Feb. of 1994, a Reef Ball (tm) was constructed on site in an outdoor aquarium designed for sea turtles. In March of 1995, a Bay Ball was added to a smaller touch tank display. In May of 1995, an Oyster Ball (tm) was also added to the touch tank. Model Reef Balls (tm) are in the saltwater aquariums inside the nature center. The project was under direction of the staff marine biologist.
