xenia not looking good

hi i have a small 26 gallon bowfront tank i have a small three poylp rock of common xenia in my tank it has looked great seince i bought it , lots of movment and constant pulsing from the tips. I do partial water changes weekly and put trace elements in the tank for the corals right now im using "Reefplus " by seachem. All of the sudden i come in today and the coral has changed color from a tan to more of a brown and almost none of the heads are pulsing. is it dying , any recommendations ?

 

test ur water

 

This is like the 4th thread about Xenias not looking good this week. I'm betting the reason you've only received one reply is because people thought they read this already. The folks on this forum are typically much quicker to reply.

Please test your water and let us know the results. Temp, SG, Ammonia, nitrite and nitrate. What type of lighting do you have? How long have you had the Xenia? How long has the tank been established? I'm not sure what "Reefplus". I would stop dosing and do a water change.
