Here is one opinion for you:
May I assure you, with your enthusiasm and the dedication in time you plan to spend with this hobby, there is no way I could say anything but... GO FOR IT. You will do wonderfully. And go all the way... coral reef and fish!
There is much to learn with fishkeeping (and all the accoutrements)! And, while getting up to speed, there no doubt will be some problems to face; but, this is the way each of us has progressed to the place we are now.
You are very wise to do a lot of research up front. Hang around SW
fish stores, and ask lots of questions to everyone willing to discuss her/his tank. You will begin to hear contradictions,; invariably there are two ways to do something. At this point, you will find yourself researching more and more. The internet if full of info; of course, aquaria books are plentiful.
My suggestion to you is to purchase at least a 75g and get it cycling. This process will psych you up and allow you the 4 - 6 weeks time the process takes to read more, learn more.
Plan on going slowly. I think most anyone would offer this tip to you. Something this exciting, maintaining a coral reef, does not happen after one trip to the fish store. It takes lots of time (which makes the challenge that much more exciting)!
Gracious, go for it! And, if you are able, depending upon how big the stars are in your eyes, possibly have the tank you purchase drilled and a wet/dry added, or purchase one already designed as a reef tank. Or, look for one used. Many folks begin this way. (Be sure to see the tank you purchase used filled with water.)
Good success, and I cannot wait to hear your excitement as you proceed. You will love it all.
