well if you want a tank like marc (aka melev) reading his logs on reef central and on his website is a great start.
Anyway, that tank of his is a 29 gallon. If you want a tank like that, its perfect since you can follow him, doing the same thing another sucessful reefer did or something similar, can help with sucess
Of course, we can still help you a bit
There are 2 main things in a photosynthetic coral reef tank that is needed, corals are different so they like different needs. Number 1. Lighting, this applies to all photosynthetic corals, but different corals want different lights, so take a look at a few corals around on the web, come back and ask us if they are easy to take care of etc. Personally, i like LPS corals the most (large polyp stony coral) but it all comes down to individual taste. Number 2. Flow, again depends on the coral, there are many ways to get flow into tanks, just to name a few there are impellar powerheads (cheapest) propellar powerheads (i think these are the best for smaller tanks) closed loop (no comment, ive never used these, these are probably the best looking cause if done well, you wont see the pumps etc).
I hope that gives you an idea of corals, so, first things first, go to your lfs or go to online fish stores or you could just check out a few of our members reef logs. If you see a coral that catches your interest, write down the name and if at all possible, a picture maybe. After you have picked your corals, pick your light and flow. After light and flow find a place where you can get live rock. Once you know what you want, and you know where to get it, youve done your research on things youve chosen, then you are ready to get started. Oh and btw, when i say "pick" i mean just write it down for remembering it later, dont buy it yet lol. Ask us plenty of questions about the products and life you have chosen, google it as well.
It would be great if you wrote out a log on this site for people to see so what you did can help other people out.
Final word, for saltwater reef tanks with a substantial amount of live rock (1-1.5 pounds) doesnt "need" a filter. Of course having a filter is great but there is a responsibility to it. Dont use the bio-wheel. If you will clean the mechanical filter once every 1-3 days then use it, there are great benefits to using it, but if your not going to clean it, dont use it. Put your chemical media in the filter.
Anyway, good luck with everything
