Next house I am putting in a fish room for sure. 

If your doing this all your self, and it looks to be the case, you are well more than able to take on the LED build and go a DIY route.  I built a LED fixture from the ground up including the carpentry on a suspended canopy hood over a year ago and have never looked back.  The full spectrum etc etc is just a ratio of LED colors and very easy to incorporate.  I bet you could purchase all the dimmers, LEDs, heat sinks, cooling fans etc for less than 1800 and have better light and control than you can imagine.  The ONLY issue in my mind, is programming a controller to run the PWM (or analog) dimming control over the lights.  Commercial options exists which would add a little to the price.  I went the route of a ReefAngel controller and I have extensive experience in this and in writing code to run PWM dimming LED's and arguably have some of the most sophisticated lighting programming available running on my tank, and tanks across the world with people using my source code.  I would be willing to lend a hand if you choose to DIY.  In terms of it looking clean, its all about how much time you want to spend being careful with wiring, solder joints, etc etc.  If you can tape and sand drywall to a smooth paint finish you can make and LED that looks very very clean indeed.  

Let me know if you have any interest- your more than welcome to come check out what I did and see how it runs etc.  The LED's of course save you significant dollars in bulb replacements but  I think people sometimes forget to add in the cost of the electrical bill.  Running 6 or 8 250 W MH bulbs is going to be well into the multiple hundreds of dollars a year in electrical service charges.  LED will cut down so far it will look free.  And frees you up to run whatever you can think of from your 60 A service.  8 x 250 W bulbs requires 17A service feed all on their own .. not that I am at all certain you would need 8... but just a number.  DIY LED can be had for the cost of a nice T5/halide combo and if your willing to add some build time for this, you will actually NOT spend more money upfront and save a ton down the line.

The sump?

And good call on the jager heaters too. Josh from The Aquarium told me to give them a try and they have been very consistent and accurate for me.

Imbed some low power color shifting LEDs into the red top and dividers and then when you light it up the dividers will carry light and glow all the way down through the sump.  Then again, this may not work so well as they may act as a light pipe and not really glow from the sides... but it would look soo cool if it worked!  

And Jager heaters are and have been one of the best for 20+ years.  Not even that expensive really.

Thanks
