Short summary

Higher levels of CO₂ and phosphate increased the relative growth rate, nitrate uptake rate, soluble carbohydrates, and soluble protein in a golden tide alga (Sargassum muticum), but the combination of these two levels did not promote growth further. Our results indicate that ocean acidification and eutrophication may not boost golden tide events synergistically, although each one has a promoting effect.
