Coral bleaching!!! Help!!

Reef2187 · Jan 21, 2017

Hello guys. Yea have had this chalice for around one year. It started at a quater size and now it's bigger then my fist. It was doing great. All of the sudden it started bleaching big time. Nothing has change in my system. I lowered the light intensity but that did not help. All parameters still the same. What should I do? Should I move it? Will it recover? Should I frag the remaining good pieces?

Yea youll probably need to frag and move at this point.
Did the flow change or slow down in that area?
Any Algae break outs, (bryo)

No algae at all. My flow did change. My wave maker broke. But it started changing a couple days before it broke. Maybe it was just not working the same or it was having problems.

Yea it's a possible one. They do need flow.
I have an unmounted chalice right now losing some flesh.
Beyonf that if evetry thing else is ok I couldn't guess save some trace mineral problem.

My old colony was like that. I broke off all the bleached parts off. And broke a good piece and place on a different spot in the tank. Now it's doing well

I broke the piece and placed it on my frag rack and on another piece of rock wanting to see is it maybe something messing with it. lol couldn't figure out the chalice just didn't like the left side of the tank

Everything else in the tank look ok?

No alkalinity spikes? From your original picture it looks less like bleaching and more like the skin is sloughing off and torn like SPS look like when they don't aclimate well or there is a spike or sudden drop in alkalinity. It would be strange if it was the only one affected.

Did any salt creep fall off onto it? Salt creep settling on it will make a healthy coral look like that in less than a day.
