LOL thanks, but I'm by no means the expert ;) Just been around a while and still remember how I felt with setup. Here is a good article:

But if you want something to just get you started (assuming you are not going to do a sump), then: you need just 6 things: Tank, sand, rocks, powerhead, saltwater, & a dropper test kit to monitor your cycle.
- step 1 is to get your sand. Avoid crushed coral; go w/ Aragonite or something finer. It doesn't have to be live (imho, live sand is a waste of money) -- rinse it out (I rinsed my multiple times w/ tap until the water ran clear). The amount depends on how much you want....I went with just enough sand to cover the bottom.
- Next get a good mix of live and base rock (you need 1-2lbs/gallon). If you don't care about a quick cycle, you can save money by getting all base (dry) rock (my 125g started w/ all dry sand and all base rock).
- Fill w/ saltwater (1.024-1.026), and just stick a powerhead in there for now to get movement. Toss in a piece of raw shrimp (or a cube of mysis) to kick off your cycle. While waiting for it to cycle, do the rest of your research on equipment.
You can gather the rest of your equipment -- 1 or 2 more powerheads, a couple of heaters, the hob skimmer, lights.
