Many of the algal fragments doubled in size in one week with a maximum growth rate of 17.4 cm/week was recorded (West and West, 2007), with optimal growth of over 20 mm/week at salinities above 20 ppt and temperatures above 20C. A cold water strain of this attractive tropical alga, possibly developed from plants that initially originated from Australia, was selected for by aquarium managers at the Wilhelma Zoo in Stuttgart, Germany in 1980. That initial methodology was modified to treat contained patches with a solid form of chlorine.
