I have a question about the cycling process. I have a 30 gallon tank with about 11 pounds of live rock. It has been running about 2.5 months the way it is. Yesterday I ordered 20 more pounds of live rock and 20 pounds of live sand. How long does it take for a tank to be fully cycled, and when can I start adding corals and anomenes. I don't have a protien skimmer yet, but I was told to not worry about it until the tank is cycled.
