Calcium is a major constituent of coralline algae, the skeletal material of hard corals and the skeletal needles of soft/leather corals. In many cases too low a calcium concentration retards coral and coralline algae growth.
Magnesium is present in natural sea water in a fairly high concentration (1350 - 1500 mg/L) and is an essential element of chlorophyll which is necessary for photosynthesis. Without photosynthesis plants, algae and coral would not be able to survive.
Strontium plays an important role in accelerating the growth of calcareous algae (coralines) and corals. Natural seawater contains approx. 7-9 mg / L of strontium. As the growth of corals and calcareous algae goes hand in hand with strontium and calcium depletion, depletion of calcium usually means strontium depletion.
