Okay, so I'm new to these forums and don't know if I'm posting this in a proper fashion or not; if not, I apologize upfront!
My wife & I are the proud caretakers of a 75 gal mixed reef w/ a 30 gal sump/refugium. Our system has been up about 2 years. Unfortunately, our little ocean suffered about 5 months of neglect and we are in the process of getting everything back in business (this system has bounced back, to my surprise, with amazing results)!
Upon my initial "cleanup" I discovered this growing on the bottom of a dead brain. I placed it in the refugium. My question is... What is it?? Should I remove it?? I've never seen anything like it. Any help would be greatly appreciated!!
