Ugly coraline or something else

[USMA36]

i have his hard dark green algae covering my rocks. Some say a type of coraline. I think it’s ugly as sin. Is it coraline or something else? It’s hard and doesn’t scrape off. Seems like it’s part of the rock. Pic taken with nights out to show true color.

Have no fear, it's part of cycling.. eventually that green will convert to purple coralline.

New tank syndrome, just give it some time, dry rock takes longer to cure- no rush, take your time. Water changes help(for me)
