Firstly welcome and good luck with which ever tank you choose you will get a lot of different advice a good first step is to spend hours reading all the different threads in here so you can see what mistakes have already been made and how they made them and I mean everything from fish selection to discease to cycling a tank also follow the BRS 52 weeks reefing in you tube and research everything now is the time to do all your reading and research so much easier to have the knowledge before you start than to try and do it all at the same time .
Good luck and take it slow and enjoy watching your tank evolve .
