ELOS System 120
My tank is an ELOS System 120. I've had it for about 2 years now, and the only things in it are literally, rock, trochus snails, nassarius snails, some corraline, tiger pods, mysis (might all be eaten), and a scarlet cleaner shrimp.
I started the tank with no seed rock, instead I added pods and such from various sources after dosing my tank with ammonia for a few months to bring up bacteria levels. The only hitchhikers came from my dumb trochus snails (corraline and a bit of algae).
Last year, a Bellus Genicanthus that I didn't quarantine came with marine velvet, killing my 5 ventralis anthias, the bellus, a handful of trimma and eviota gobies, and my clownfish, within a day. I had the ventralis for over 5 months at that point, the gobies for more, and the clownfish for 3 years. I have been fishless for 6 months or more now.
In the meantime, I gave all my corals away (mostly to BAR members and new reefers), so now I'm paying a ridiculous electricity bill to keep some snails =P
I'm trying to finally get my house remodel underway. Lots of unfortunate problems (architect was diagnosed with leukemia halfway through the project, but thank goodness he is doing better now) had kept this from happening earlier. Once the house is done, I will be moving over there with the tank. I'm thinking in December.
The tank will live on an island, I'm going to actually have the contractor reinforce the floor under where the island will be, and probably have him get a woodworker to build the stand (to look attached, but not actually attached). I will run piping through the crawlspace to a RODI water resevoir for topoff, a clean saltwater mix for a continuous water change (I need to buy a litermeter III), and maybe some piping to some remote fuge and chiller in the closet (might not be needed). I'll also have GFCI outlets under the floor there as well, so I won't need to run wires all over the floor. And lastly hanging a pendant above. I'm thinking of biting the bullet and going for a full LED replacement for my halides.
If anyone has suggestions on LED's as lighting for SPS (and even criticism for the cost vs. electricity bills), please let me know! I'll start updating this thread with the tank plans. For now, no new animals.
I believe aqua illuminations is safe (I vaguely remember that they pay orbitech or whomever, royalties). I've heard lots of good things on those fixtures. Their design in general looks pretty solid. Way better engineering considerations wrt thermal loads than PFO. Not sure if the drivers are better, but I haven't heard any complaints in that department either.
They also look pretty nice and will fit in with the elos decor

You can actually run commands to the unit with RS232, so if you are slick, well..you can get slick 
They have a handful of reasonable measurements on their site. I wish they used a lumenarc or lumenbright to compare to vs the spider reflector 250.

Great to hear that the tank is still up and running and that things are back on track with you.
God you take great pictures. Even with nothing in it, it looks like a work of Art (pun intented)
As long as there is no color control of the LED itself it is not a violation of the patent. This is why there are now a dozen or so companies selling LED's for aquarium usage.
If you have a grand to burn the new plasma lamp is insane. I saw them in use at the MBA last weekend and they rock. The shimmer lines are much brighter/tighter then that of a MH.
Are those the tiny bulbs that were like the equivalent of a 400w MH? I saw the video awhile back and have been waiting to see when they were gonna be used in any sort of aquarium application.
someone doesn't follow Reef Builders.... www.reefbuilders.com
That is them but the actual field numbers are better then a 400w from what those who have seen the data tell me.

Great to see the tank Art 
No doubt the shimmer lines are insane, but it isn't because the MH isn't capable of them in principle. MH shimmer is mitigated some by the multiple reflections used in these new fancy reflectors. The plasma in the RB link uses the reflector, but only in forward propogation. MH has a bunch more due to every reflective surface above the plane of the bulb. That said, the efficiency of the lumenarc in the article is lower then it's potential because it is well above all the focal plans of the "psuedo parabolas". Tempting to model the reflector and ray trace the intensity at various internal heights. I may have just found a project for me to model
Technical OT mumbo jumbo I'd be interested to know when they come out with other "colors" by doping other nobel gases and metal halide complexes:-D

The color is fantastic BTW. No doubt MH can produce them, it's one of the most common replies when some one first gets one 
Looks very nice Art, if anything it's probably good that you don't have much in the tank that needs taking care of while you're doing a remodel.
As to the LED bit, I'll let Tony get into specifics. But given the legal/patent issues currently surrounding LED lighting for aquariums if it were me I'd stay away from them for the time being.
