Schneider and Erez (2006)

Rates of net photosynthesis were measured in colonies of the coral Acropora eurystoma in sealed temperature-controlled chambers (24░C) under daylight conditions (constant irradiance of ~350 Ámol photons m-2 s-1) at different pH levels over a period of about 2 hours. Reduced pH conditions were obtained via the addition of HCl into seawater.
