What’s wrong with my chalice?

[122buster]

I just bought this chalice two weeks ago and I notice these brown lines underneath it. Help!?

Hmm...haven't seen that before but then again I don't have a lot of experience with plating corals.

Looks like Tissue Necrosis.

Looks like Tissue Necrosis.

What is that ? And how do I fix it?

With that much damage I don't know if you can save it. You may try lowering it to your sand bed to see if you can save some of it. Sorry

The coral's tissue is dying. Sometimes related to tank conditions sometime flow... it looks like a newer tank...but I also see there's air bubble under the chalice rim and power head so it may be too much flow.

Well that’s a big bummer, was really loving that coral. I went ahead and put on the opposite end of the tank on the sand bed, fingers crossed. Anything I can do to try and help it?

Yea don't freak too hard. I don't see anything going on with the polyps on top.
Reach under and see if that stuff wipes off. It could be just some kind of die off of micro organisms and such. That look like cyano to me btw feeding on it. I'd bet the flow under the coral has changed from where it was and where it is now.

That chalice is kinda bulletproof IME , so if it starts to let go, just pop a pice off and put it some where else in the tank.
It's a Hollywood stunner I believe.

Thank you for all the information, do they prefer a heavy flow or low?

Low ish will do, but will take anything up to direct flow from the powerhead. It is an sps after all and can take a lot.
