A "wide variety of corals" will have a equally wide variety of demands.
As you know I am not a proponent of extreme wattage, which has been one of the reasons for doing my survey Id suggest to have a look at that. Anyway, again I would recommend easier to keep corals and usually...the higher the light requirements the more difficult to keep.
For example a HL SPS tank will consume a of allot of calcium, so a calcium reactor may be in order and depending on your physical location the heat from the lamps and pumps usually transfer to the water so If your in this league.. a chiller may also be called for. Keep in mind a wide variety can really be *a wide variety* but the long term costs of operation is extremely costly believe me!
