SPS dying don't know why

[hpfusion]

My millipora is dying and i don't really know why. All the water parameter are good because all my other coral are growing really well. The only thing i could think of that could be causing my coral to die is lighting spectrum. The millipora is under a PC light and i have close to a year now and the bulb hasnt been change. Have any of you experience this kind of thing before. Since it's dying the base of the coral is bleaching, so could i save it buy cutting off the piece that is still good.

SPS are kind of fragile to say the least. I've kept a few low light loving sps in my old fuge under PC's and never had a luck with color. They lived but didn't look like they do under MH's.
I've always changed my PC's at 9 months..
