    Hello all,

    I am wondering if this is an emergency. I was away for 2 days on business and when I came back, my purple live rock has turned brown, almost looks rusted. The sand on the bottom has also turned brown. Is this algae? Or something I need to take care of ASAP

    I'm not sure what it is, but a picture would help. How old is your tank, could it be diatoms? Have you added any new equiptment recently?

    Sounds like a diatom outbreak, normal for a new tank to go through. Once all the available silica gets used up they'll go away, not much you can do.

    What do you have in there? They should be okay, just keep an eye on the params.

    Sounds like diatoms. Your tank hasn't cycled completely at 2 weeks old. What are your water params?
