Hey guys. I'm new to the salt game. I started my nano with one large live rock and one small. Large is various shades of blue and a little purple and violet and red on some areas. I actually never thought anything of the blue rock until today. I looked on line and I can't really find anything. Can some one tell my why my rock is this way?

My live rock is also starting to turn blue so your not alone. I have no clue why

It’s not man made. It’s real blue coralline algae. My son just bought some live rock from a guy that’s breaking down his tank says he’s too busy to care for it anymore. Long story short he got a big rock with blue coralline algae. Lots of purple & pink rock too but the blue was beautiful. You can tell it’s not painted
