Well, there are several threads on here as for equipment needed. Also, since you are new to the hobby, try reading a few good books FIRST! Then research your equipment. The conscientious marine aquarists or new marine aquariums are good starting points. From there you will understand what the system, tank and cycle is/should be.
Then, once you obtained that knowledge, specific questions about products can be asked. to answer you quickly, heres the rundown:
1. Tank, stand, canopy
2. Lights (yours is fine for FOWLR) T-5, PC, MH, VHO - your call
3. Heaters (sized for your tank)
4. Powerheads (15 times water change per hour)
5. Substrate (Sand)
6. Live rock (1.5 lbs per gal) - this is your biofilter
7. Mechanical - is what it is.
8. Protein skimmer
9. Thermometer
10. Cleaning kits
11. Test Kits ( Am, NO2, NO3, Ph, Ca, Ak )
12. Buckets
13. Refractometer/Hydrometer
14. RO/DI Water Source
15. Salt
16. extra PwrHead/Heater for mixing water/water changes
anything else I cant remeber - someone will chime in.
Start with a book or two. It will be worth it in the end. Plus its a good reference point whenever you have questions.
Good Luck!
