What is this on new frag?

[Afkomjorgen]

Hey,

I just got a new frag ( very excited! Getting my first sps corals)
I noticed that it had something on the side of it
Lfs said detritus
It’s crusty and hard feeling but broke up quite a bit in the Dip
Any ideas if it’s an issue?
Sorry I couldn’t get better photos

That’s ok! It’s in the tank now anyways lol. I don’t have a qt set up ‘yet’ (next project)
Anyways it’s still pretty closed up since I got it. Gonna experiment with moving it. I think I took the ‘likes light and waves’ too seriously when I put it at the top of the rock work in front of the wave maker lol
