When we set up our tank we purchased live rock and sand from a lfs. The rock had a skeletal structure of some sort of coral on the back. White and looked dead. Well after a month of no light our photon v2 came yesterday. I was doing my normal inspection of the tank mostly looking at my torch flowing in the current and what I thought was a dead coral on the back of the rock is glowing. Has this happened to anyone before? I’m really curious to see what this turns into. It’s about the size of a pea right now. Looks like I’ll blast it with some reef roids when the lights go out.
