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.

Red Sea’s new T5 REEF SPEC™ Lighting range is the result of extensive testing into the needs of corals within a reef aquarium environment. This high quality German-made lighting is proven to provide the intensity and color spectrum required by even the most demanding coral species, commonly known as Small Polyp Stony Corals (SPS). These corals include such species as Acropora, Montioporaand Seriatoporaand have far more exacting requirements for lighting than soft corals.
