Gattuso et al. (1998)
Calcification rates were measured on corals grown in synthetic seawater. Changes in aragonite saturation from 98% to 585% were obtained by manipulating the calcium concentration. The concentration of CaCl2 was set according to the desired aragonite saturation level and both Na2CO3 and HCl were added in order to obtain the desired values of dissolved inorganic carbon and total alkalinity, and the NaCl concentration was then adjusted to respect the chlorinity (and the salinity).
