Blue‐green algal growth frequently occurs in water with relatively high pH and high levels of organic carbon which are related by the pH‐dependent ionization of inorganic carbon. This relationship, which may regulate natural populations, was examined using a factorial experimental design in which the metabolic response of Anabaena flos‐aquae was measured as a function of pH and total inorganic carbon. The concentration of the products of ionization were calculated. Algal responses were determined manometrically as rates of photosynthesis and respiration. The overriding factor regulating the growth of Anabaena was pH, and no obvious relationship was found to exist between oxygen evolution or uptake and the concentration of any form of inorganic carbon.
