It sounds like a nutrient issue, the algae and corals losing color is common in new tanks. How old is your tank?

 

[Fish Think Pink]

how old is your tank?
how long have you had the corals?
what are your water parameters?
what are you feeding your corals? ... and how often?
what changed?
photos (under white light preferred) ?
