Orange Death?

I dont think that is the dreaded orange death.
It looks like some sort of algae growth.
If you scrape it off, can you still have coraline underneath or does it all come off?

Nope seems like there is nothing growing under the orange algae...

to me, that doesn't look like the pictures that I've seen on RC and in some articles I checked out.

If it starts to spread, you might worry, but that just looks like algae to my inexperienced eye....
