Other things that you can do is to put the light higher and slowly lower over the course of 3-4 weeks. You can also buy several sheets of window screening and put 7 or 8 layers over the top of your tank and every week take off one layer. Simply shortening the lighting schedule may not be enough given the extra intensity of the light - it will definately help but may not be enough. You may have to move your corals lower in your tank and slowly bring them up again over a 3-4 week period and at the same time increase the time the lights are on.
