SPS color question

[Marlin65]

I am running a 14.000K bulb no other light and it is 2 months old.
I only have frags no bigger pieces and the two that are browning are both acros I think.
I will try to post some pictures later.
All my frags are about 10" away from the light.
I did have a cats paw the pink one start bleaching on me but it is recovering in the btm of the tank.
The rest of my stuff is really growing and has lots of color. It seems to be just the two pieces. One is a tri color and the other was kind of brown when I got it but had blue tips that are now browning a bit.
I don't run a phosphate reactor though.
Right now I am about to move things to a larger stand and adding a bigger refugium to be mounted to the top. I still like my sand and want lots in my fuge, but if I need to make a change now would be a good time.
I also have a few clams so the Zoe-vit is probably not the way to go for me.
I don't use any of the product now as I don't know enough about it, but thought it might help a bit with my color.
