IMO i feel the same as pasfur, you need to do more research. the fish will be sensitive but the corals even more so. if i was in your shoes i would take the time to read about anything and everything saltwater related. salinity, alk, ca, mag levels, lighting, flow, fish sizes and compatibility, depth of sand, there is just to much to list, and that right there is a good couple weeks of reading to understand it properly. i would just research while im saving up funds for this investment. i say investment because this is meant to be long term.
i dont intend to discourage you, i just wish to properly inform you and if you have any questions feel free to ask, i would be glad to help you out.
