Cyphastrea Help

[chrisdafish70]

My cyphastrea has been doing great. I just noticed it started receding. Should I try and get rid of the dead area or leave it? Also any suggestions? I noticed my salinity was low from my water change.

They'll sometimes grow back over themselves if the die back. How low was your salinity? Is that the area where you poured in the new water?

I wouldn't try to remove it, get/keep parameters stable and it should grow back over it pretty easily
