Im not sure what is normal or not when watching live rock cycle. This live rock has turned from an off white color to a reddish brown, along with some green sprouting. Even the dry rock to the right of it which was completely white is being taken over. There are even other pieces getting other colors like pink, red, and orange to them. Is there anything I should be concerned about? There is adequate water flow in the tank and a skimmer along with refugium in the bottom.
Good or bad?
