please dont make me post another graph showing the actual spectrum of photosynthesis, i have posted it multiple times on this site showing at what spectrum corals photosynthesize at. most of natural sunlight dose not penetrate down very far and reds, yellows, and greens are quickly absorbed and do not even reach the corals. trees use sunlight to and they do not use green light either for photosyntheis, they reflect it. same deal with corals.
