There are likely twice as many ways to set up a marine tank as there are current aquarist (and probably 1/3 of them work). The hobby is still relatively new (commercial synthetic salt has been around for less than 60 years and for half that time we were lucky to be able to keep
fish alive -- forget corals or the more sensitive invertebrates). Understanding an aquarium cycle is the first step (sometimes it feels like you are getting a biology degree along the way) and critical to a successful tank, regardless of what you will keep. Suggested reading:

The
newbie sticky I referenced in your other post has links to a couple of articles and discussions on setting up a ceph tank but you need a basic understanding of the marine environment before you jump into specific habitats. Many of the conflicting opinions you may read are not really in conflict but are biased toward keeping different animals. A FOWLR (Fish Only With Live Rock) tank is a simpler environment than one needed to keep corals and keeping soft corals is different again than keeping hard corals. The common component is water quality but how to maintain the water for the animals varies for both type of tank and hobbyist preference.
Once you start getting your feet wet (and mind confused), try to formulate an understanding of how the equipment mentioned fits into the environment you are trying to create and then ask questions about that specific environment. We will try to give the best answer and the reasons for including or excluding hardware. Budgets, space and preferences are often limiting factors but don't make time part of your consideration. Patience and learning to enjoy the small changes you can observe will allow you to enjoy the hobby and its animals far more than quickly setting up a tank and failing repeatedly until you either give up or finally have success. Avoid quick start, quick fix and other magical solutions as they are more likely to do harm than anything positive. There are a couple of well known sayings in the hobby that emphasize the need for patience and learning the environment you are creating. Google, New Tank Syndrome for an understanding the problems of overloading a new tank,
nothing good happens quickly in a saltwater tank for the awareness of the need for patience and
Multi Tank Syndrome (more commonly achronymed as MTS) for what happens if you get hooked on the hobby and understand the need for different environments
