hello all. I have some live rock cycling for the past 6 months and just noticed something growing on it any ideas???

Are they harmful

Any one knows what this is on my live rock

I think it was red bubble algee so I threw the rock away that had it. Didn't want to take any chances. Thank you everyone.

It does look like that is that bad

Any help will be appreciated

its growing on one of my rubble rock in my refugium
