Don't want to sound negative or anything but it kind of sounds like you don't know alot about corals. Lots of people now are switching from a Reef tank to a FOWLR tank (Fish Only With Live Rock). I've heard too many stories of people spending hundreds or thousands on Corals throughout months and then within 2 days they all die from a spike in the water. Just want to let you hear something negative so you can make the right choice. Also if you are a true hobbyist it won't be hard to learn what you don't already know. Good luck to it all. If you are going to do a community FOWLR tank then take a look and my aquarium and you'll get an idea of what will go together.
