Bubble coral receding/melting

[FollyFish]

When I looked a the bubble coral yesterday I noticed that it was touching rocks so I moved it. Today this is what it looks like. I have done an coral defense dip which states that it will treat microbial infections but is there anything else I can do?

How long have you had it? Could it be too much flow, or not enough light?

I have had it for over a year. The area has very little flow the area is well protected and mid range light. I know that the damage is because of rubbing against a rock. I am hoping to save it.

I doubt this is solely from brushing against a rock in gentle flow unless you (or something) recently moved the coral up against the rock.  (ie it didn't originally grow there and wasn't familiar with the rock)

 

How old is the tank?

 

Can you post a full tank shot?

 

Can you post you test results for phosphate?  (Everything else you test too.)

I ended up moving the coral to a new area in a corner under a power head. It bounced back and now has a second mouth. It has open back up and is being happily agressive as it should be.
