Abstract
These corals were grown in seawater spiked with CaCl2. Growth rate increased greatly with a moderate (25%) increase in Ca2+ concentration but this increase was less marked at still higher Ca2+ levels. The growth rate declined at concentrations above a 50% increase. This suggests that Ca2+ may limit growth at concentrations near seawater. The Sr2+/Ca2+ ratio in the new growth proved to reflect that in solution. The same trend was followed to some extent by Mg but Na showed no variation at all. This demonstrates clearly that some elemental variation in seawater is likely to be reflected in the composition of scleractinian corals. -from Author
