Lobo losing color or flesh?

[tallreefguy]

About a month ago, I bought a lobo from a new LFS. And ever since, it's been developing white patches. I've since moved it into a shady area, but any part still exposed to light loses it's purple color.

I'm starting to get frustrated because it's the only coral that's doing it
Tank param's at:
78-81 deg.
1.025 saltinity, 7.8 alk, 400 calc, 1250 mag, water changes every 2 weeks w/ Red Sea salt, fed daily. Nitrate 0, phosphate 0.02 (hanna)
180g AGA tank, outside bulbs are 2x250w Reeflux 12k (6+ months old) @ 8 hours, center is 400w reeflux 12k @ 5 months old for 6 hours.

I'm having this problem with a trachi

way too much light for this guy. 400 w and 2 250w. no. no . no. they like low light. put it in the shade and it will recover. unfortunately if you have sps and need the high light, you may need to get rid of this guy. they also take a fairly long time to recover so be patient with the coral.

Ok - I had a feeling but didn't think it needed that low. I do have sps. I will move it to the shade on a 250w side and observe.

Thanks!
