I got a 29 gallon BIOCUBE, and Saturday bought 20lbs of uncured live rock. I have heard some people say to do weekly water changes and some saying not too. Some say run a skimmer and some say not to. What should I be doing? I know I am looking at 2-4 weeks before I can put anything else in the tank since I bought uncured live rock, but I want to make sure I do things correctly for this tank!
