inquiry Coral polyps actively control the precipitation of calcium carbonate. This is inferred from daily and seasonal variations of calcification rates, which produce density bands in the coral skeletons, similar to tree rings. Due to this biological control, some corals are able to calcify in waters with relatively low pH.
