    These pictures kinda suck but there is noticeable "lightening"
    Before

    Now

    Tho only recent changes are a new T5 light fixture with actinic lighting which i gradually added (4 days) and a recent boost in Mg which was low but I just got a test kit so I fixed that.

    Current params:
    Ca: 420
    Mg:1400
    dKh: 10
    Temp: 80.1
    pH: 8.06
    Salinity: 1.025
    NO3: 0

    Also all other coral including clam and other SPS seem normal and healthy.

    If the color is fading, the coral may be bleaching. If it's RTN or STN, the flesh of the coral will come off of the skeleton.

    Yeah its just fading. So will it bounce back because this particular frag had really started to take off?

    What kind of lighting did you have before you got the T5s?

    All I see is a difference in lighting..... It definitely has some growth difference too

    Sorry, it's not clear to me. You had MH lighting and then you added a T5 supplement, or you switched from MH to T5 all together?

    looks like bleaching since its the points closest to the light that are losing color
