I would first get a book and start reading about it... Do some research and plan on spending money. I started (after a 10 year hiatus) with a 32 gallon hex (used oceanic) with stand and I have already spent 400-500 dollars... Conscientious Marine Aquarist by Robert Fenner is a great book to read up on this hobby... Good luck!
