apparently there is still a lot of debate about whether corals utilise red light, I myself haven't got a clue if they do or don't but when reefers such as David Saxby (the boss of D-D) uses red light on his home tank and from what ive read World Wide Corals use red light in their show tanks then im tending to lean towards them rather than Red Sea who are basically just marketing a light.
