Favia looking sort of brown

[Sam115]

Hi everyone. I moved my corals tank today and I noticed that my favia got really brown. Any ideas?

Medium to low flow, medium light

Or something must have stung it. Can you upload a better more brighter photo?

Or check the salinity... happened to me once...

First thing you should always do when a coral is looking kind of off is test your water, 99% of the time water chemistry is the cause of the problem.

I just did a decent sized water change so the salinity should be fine. He is more towards the bottom of the tank. He has always been positioned in the middle/bottom of the tank. Should he be moved up more?

I can get a better picture when I go back home today
