You've got some great advice there from brian's reef. You'll find that most reefkeeper's will have the fish population at a minimum. If you're adamant about keeping a lot of fish, go with a dwarf angel, small tang, goby, blenny, clownfish, and hawkfish. This combination of community fish would be good for a reef and would not create a lot of wastes. Plus, you'll be able to introduce all types of tank cleaners. If you decide to use live aragonite (which I would recommend), you'd be able to add fish in as little as a week and corals in 2 to 3 weeks. Although, it's still a good idea to take your time. Skip on the goby though, because it will sift the sand for fauna. Remember not to use any bio balls when setting up a reef tank. Live rock and live sand are the most natural processes of denitrification. Adding any type of wet/dry filtration will double the process and upset your system. Use the wet/dry as a sump instead and check out other filtration methods. Good luck.
