Torch coral tentacle color fading

Checking, some of the tentacles on my TORCH CORAL have turned to a white/clear. The Original color was brownish/green. I do not think it is bleaching, my lights are approx 5mo old and the torch has been in the tank the entire time with these lights, ideas??

 

what brand of halides are they? also, what (if any) foods are you feeding your torch and how often?

Unfortunately their are variables that can affect the amount of light available to your corals. Turbidity, elevated dissolved organics, tannins, salt creep on tank glass, articulate matter, gametes and toxic compounds all can reduce the amount of light(PAR, PUR) being available to your corals.
One or more of these variable may be responsible for the bleaching, if this is in fact what is happening.
