:welcome: to the board.
Like already mentioned you have a fairly long wait before the tank is suitable for adding fish so you have plenty of time to learn more about saltwater fish keeping. You should get a set of basic test kits (ammonia, nitrite, nitrate, pH) for starters. You will not need to light your tank during cycling as this will only promote the growth of nuisance algaes. Do you have any kind of filter? If you are planning on only using the live rock as your filter then you will need something for water circulation like a powerhead. What kind of tank and size did you set up?
