Hi, so I’m starting over due to a possible contamination. I was removing everything from the tank and noticed these white crystal like things growing on the bottom of my live rock that was sitting on live sand. I’ve done research but I am not sure if this is dead coralline. Anyone know what this may be? Thank you.
