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).

Marubini et al. (2008)

Six 20-l aquaria were used to hold nubbins of the branching coral Stylophora pistillata for 8-day experiments under three different pH and two concentrations of total DIC for each pH. Chemical treatments were achieved by continuously dripping the required amounts of NaHCO3, HCl or NaOH into each aquarium with a peristaltic pump from solutions made up daily. Bicarbonate-ambient seawater (2 mM)
