Hello,

400W over a 33 gal should be fine. Just watch our for the heat from the lamp and some corals will need a shaded area to prevent bleaching. You may need a filter to prevent UV from killing your corals -- especially for higher colour lamps.

10000K vs 20000K vs ???K ... its a personal preference. Green accents on corals like elegance and frogspawns will look prettier (at least, I think they do) with the higher colour lamps. So....20000K should be fine.
10000K is like snow white with a blue tint.
