Strange growth on LR

[netta]

Hi All
I have this strange growth on my LR. It appears dark brownish/black feathery :notsure: . The rock also have the beginnings of purple-ish coraline in spot. My hermit and emerald green crabs are all over the growth. Should I be worried? Should I try to scrub it off?
72 gallon bow FOWLR (running since 7/16)
Only my cleanup crew (6 turbo snail, 2 emerald green crab, 1 cleaner shrimp, and Chocolate chip Starfish)
My water parameters
S.G. 1.024
pH: 8.4
Temp: 79f
NH3: 0
Nitrite: 0
ALK: 300
The only thing out of the ordinary was a recent ich breakout (about 3 weeks ago)

. Fish is currently being treated in QT with copper (loss Hippo Tang, and Coral Beauty) pink damsel, neon goby, purple psuedochromis, and 2 clownfish all clear of ich ( :joy: Thankfully)
Any thoughts??? :thinking:

I don't know but get rid of those color stones in your tank.

We have live sand and crush coral in the main tank. Because it is FOWLR, I wanted to add some color. So, No I am not getting rid of it.
AllI want to know...what is the growth on my LR, not how to arrange MY tank.
Thank you

netta is asking a question about something on the lr, not questions about the colored stones.. please read more carefuly on the thread be4 you click on it

..the tank is different from others. that makes a person a leader, not a follower like yourself

..i hate it when you ask a question in here and someone comments on something totaly different about the thread!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
