Watch adding live rock after the tank is setup. Make sure you cook it for about a month. I learned the hard way after I bought some so call cured live rock and dropped it in my one year old set-up. It crashed my whole system. Wiped out all my fish and gave me a bad case of hair algae and glass anemones. Needless to say that was the end of that tank. I just started a new one after a year. Just because they say it is good does not mean it is. Sadly to say a lot of people just want the sale. So now I stick to the small fish stores.
