Haha, makes a bit of difference there. My advise would be to start slow and be patient. Nothing good comes fast in marine.
Well, Firstly we need to know what skimmer and light set u already have. For the lightset, how many 54w bulbs, brand and colour of bulb. For skimmer, what model as it will determine if its suitable to be used for the tank size.
What u will need for a simple set up:
1. Skimmer rated for your tank size + sump
2. Lightset
3. Return pump
4. Wavemaker
5. Some form of mechanical filter (filter floss/wool/sock)
Get these sorted before you think about more equipment like chillers, reactors etc. Good luck.
Also, what you planning to keep will make a difference in equipment choice. Decide if u wan corals or just fishes.
