What does lighting exatly do for coral? I understand photosysthesis is consumed by zooanthellea. But is coral with less lighting requirements why do sps
need so much more? Bc if one can makr what they need with less light why cant sps
use the same light? & if the light is making some type of algea to feed with a strong like could u use a less intense light and add what the coral makes and consumes?
