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
