Most corals are photosynthetic and approximately 85% of the energy required for their growth and coloration is provided through the symbiotic relationship they share with the zooxanthellae algae which live within the coral. In order to facilitate the development of the zooxanthellae, it is essential to provide not only the rightintensity of lighting (approx. 1w/liter for T5 fluorescents provides optimal photosynthetic irradiation spectrum – PAR), but to ensure also that the lighting provides the correct color spectrum for corals.
