Chalice looking BAD?

[billswin99]

Bought this bright orange chalice frag. It was a little black around the edges when I bought it. It seems to be spreading.

Pics didn’t come out to good but it is black on the left bottom side and spreading. The tentacles are out in the pic. Anything that I can do to help?

What's the lighting, flow and nutrient situation? You could try an iodine dip if it's got necrosis, but good conditions are what will bring it back.

I believe melafix dips are your best best...
Though to be honest, the pics are a bit hard to make a diagnosis with...
