Color loss?

[Drewbaby]

My pearlberry frag and tricolor are losing color. They are turning brown. I moved them up to a frag rack to give them more light under my T5's. They came from a tank with 250mh. What else would be causing this? My other SPS look good and are full of color. I even have some that are coloring up in my tank.

I haven't got tank params but they should be stable as I do weekly water changes of 15%. I also dose OB 2 part and mag.

Any ideas or possibilities?

High nutrients? What are your nitrate levels? Also give us a full run down on your system so we can better advise you.

Dont ever assume your water parameters are good always test. I have been keeping sps for a few years now but am in no way an expert. I test but went through a "my water is stable so I don need to test" but things got out of balance and my sps started to look bad. Do a full water test and report back to us on that. One of many things that made my sps thrive is stable water parameters SG, Ca, Alk, Mag dont worry to much about anything else water changes take care of the rest. Having 0-5 ppm of no3 on 0 ppm po4 helps with the colors as well. I feed my sps 3-4 times a week to help boost colors. I have also come expect that new additions will brown out or lose some color for a while. Not all new sps do this to me but maybe 1 out of 4 will. But given time a good placement the color comes back.
