white patches are coraline algae that are decaying... common in cycling phase....

black...i haf no idea.. maybe someone can explain on that..

IMO, maybe its debris covering the LRs...

to promote grow of coraline algae, dose calcium..if i m nt wrong..

The black part could be due to dead sponges or encrusting sponges>?

Just have strong lights, high calcium levels and high kH and you coralline will come back in no time. ;)

Always something more important than fish.
