Okay...reasonibly ideal...how about that.
I'm going to assume you want an sps
tank just because that falls more into the "ultimate" category.
For every 2sq ft of water, one 400watt M/H with an XM 20k bulb.
Also four VHO
Skimmer: Turbo Floater 1000 is an excelent skimmer...but I cant say if it is the best since I havent tested them all.
Calc reactor. This does not have to be store bought, but you will want a PH
gauge on it.
100gal sump under the tank. This would house xenia as the preferred method of toxin removal (also generate cash flow!
) and a pod haven. A water pump instead of a power head is a must. Das filtration avaliable by opening a valve. (I have this on my system right now...Its great)
A top off system of some sort.
Im not sure what else you could add that you would really need. A wave maker capable of handling at least 4 pumps would be great.
