Coral color fading...

[KrazyMandarin]

...i have had a large tank now(350) for 3 years. the tank was a gift. it took a while for me to slowly acquire everything for setup, but i did. the tank has been running for about 2 years now. I havent noticed any problems until a few weeks ago. My corals, all but a galaxea, have been fading and their colors all looked washed out. The only change made to my tank in the last year would be the lights i setup a couple months ago. The lights are considerably brighter than the old setup. I started them by hanging them about 2 feet up and slowly worked them down to 14" over a 3 week period. i asked the staff at my lfs, and they all said a little bleaching would be expected and it should only last a week or so. well its been months now and they havent started regaining color. this isn't my first tank. i successfully kept a 75 gal for years. all my levels are in their appropriate ranges, so i'm kinda stumped.

any help is greatly appreciated. i have 2 new twin girls, so i won't be able to answer responses in a timely manner. but i will answer them all eventually, so please just bear with me. i would like to say thank you in advance for the help, as i'm sure you all out there will have some advice for me.

Thanks!

if the only thing changed is lights, i think they will slowly get their color back. if they are bleaching heavily, its another problem!
