Calcium is very important in a reef aquarium. Corals use it to create their calcium carbonate skeletons, and it is also important for snails, hard tube worms, and clams. Finally, it ensures the healthy growth of purple, pink, and green calcareous algae. If calcium levels are not maintained at adequate levels, reef inhabitants can become stressed and ultimately die.
