Hey guys. I just joined up today looking to learn more and get in touch with a new community of reef keepers. So I picked up an almost dead pice of rubble at my lfs like 2 months ago for free ( why not ) and now it’s looking beautiful! But I have been looking for what it could be? Any ideas?? And I know I’ve had a bloom of algae as I’ve let my phosphates get a little out of hand when my RO broke and have used tap water, and things are slowly comping back down. Thanks in advance
