If you are starting from scratch then you might want to consider using a kit in order to get your saltwater tank set up. One that I have used in the past and recommend is the Marine Aquarium kit which comes with a 55 gallon tank and supplies needed to get it started.

If you would like to do it all piece by piece though then at least make sure you have a step by step guide. In order to get things rolling you should reference the The New Marine Aquarium: Step-By-Step Setup & Stocking Guide:
