It looks a little white.  I would add a few actinic or blue bulbs to it.  A fefugium may be difficult in that location, but something to consider.

Because of this thread I decided to try an experiment.  (with my neighbors tank)

Here is his aquarium on the bedroom dresser yesterday.

and since we can't add too much light we upped it a little.  What do you think of it now Adam?

So many responses already but I'll try.  Banana- that much light on a 90 gal is fine.  Mark, those people should be moving their corals under their rocks, not on top of their rocks.  And as the club lighting guru said, if you want algae to grow in your sump not in your tank, you must have more/better lighting in your sump.  So those people with out of control algae need better refugiums. Why is it that we all like to have our rock stacked up, then place our corals nicely on top.  Crappy looking if you ask me. 

Build caves and arches, build your rock work all the way to the top, then across the whole top of the tank.  You won't have too much light down below.  Really, you can't over light your tank.... you can however improperly place your tank inhabitants.

Personal opinion here, but what the heck...

Adam, well, I disagree.

Weimers, 84 is not that bad. Don't go buying an expensive chiller. Try running a $4 desk fan over the sump and you should be fine. Look at the other creatures in the tank. How are they acting? Many days, 84 is normal for me. In many natural shallow reefs, 84 is also normal!   An excerp from http://www.rshimek.com/reef/tempsal.htm

The article listed below describes in detail the basic physical conditions of coral reefs, and it is also worth examining.

Kleypas, J. A., J. W. McManus, and L. A. B. Menez. 1999. Environmental Limits to Coral Reef Development: Where Do We Draw The Line. American Zoologist. 39: 146-159.

These authors took measurements from over 1000 different reefs, and determined the physical and chemical limits statistically.   

The temperatures they found (Converted to Degrees Fahrenheit):

Averages: Minimum = 69.8º; Maximum 85.1º; Average = 81.(this is the average temperature of all coral reefs).
Minimums; Lowest = 60.8º; Highest = 82.8º; Average = 76.4º.
Maximums: Lowest = 76.2º; Highest = 93.9;º Average = 86.4º.

Some extremely warm and saline reefs were noted.

Extreme Reefs (Maximum Weekly Temperature in Deg. F; Salinity in ppt)
Southern Red Sea = 89.1ºF - 91.2º F; 38-40ppt.
Central Red Sea = 88.7 ºF - 89.1º F ; 40-41 ppt.
Northern Red Sea = up to 88º F; 41-42 ppt.

Those of you with Red Sea animals may well wish to alter the temperatures of your reefs.

Just a shot here but I think Adam's response could go something like this, yes the luxor light display may be too much for a 90, But I don't see how you'd fit 39 7000 watt bulbs in 8 square feet of surface area. For the hood area available on a given tank even filling it with MH's would probably not approximate the sun's intensity at high noon in the tropics. Given alot of the things we keep are not within 24" of the surface in the tropics, but there are some things that are exposed to direct sunlight above the surface of the water during low tide on the great barrier reef that thrive. And I'd Imagine that's gotta be a whole lotta light. (very technically put eh?)

Either that or it's a symantics thing. Adam said "you" will never over light your tank, meaning he knows none of us are going to arrange a Vegas style attraction in our own homes. (although I do have a minor mock up of circus circus in my basement  JK)

I was thinking about adding the same lighting setup as the one on top of the Luxor hotel in Las Vegas to my new tank. It would be 39 x 7000watts xenons + 2x65 watt actinic PC. Thats a total of 273,130 watts over a 90 gallon (over 3,000 watts per gallon). Too much?

Ritteri anemones are known for liking intense lighting (250 or 400 watt MH). Did you just buy it? Many times these anemones are kept under lower light conditions at the LFS. When they are placed in a new tank with intense lighting, it may take some time for them to adjust.
