Wow man, I love what craftsmanship of your stand and cabinet - looks perfect! Your new setup looks very nice and you have a pretty amazing collection of Acros. Now that you have gone T5, I suggest increasing feeding slowly over the next 6 weeks...whilst keeping a close eye on PO4 and NO3, try keep those two in line whilst increasing the food input. Dont feed the same stuff 3 times a day, add a variety of foods... Basically LARGE food input + LARGE waste output is what you need.
I really liked your old tank: The scape was awesome...yeah that was a sweet tank.
Will be following this one as well.
Great input. I agree. I did increase my feeding allot. My PO4 is low - .03 and my NO3 is undetectable. Should those two numbers be higher for coloration? I am finding my color to be pretty good on most acros. 
Looking great! Loving the colours you are pulling from those acros.
With regards to PO4 and NO3, what I said in last years post was that you basically increase feeding , whilst keeping PO4 and NO3 close to what they are (ie without chasing numbers too much, but not letting things get out of control). Corals in a 50G tank with 10 fish fed nicely will look much better than corals in a 50G tank with 1 fish even if the PO4 and NO3 levels are the same.
Have a look at Richards tank (runs 400w Radium with T5 and LED=lots of light+high nutrients); he has awesome colours on his SPS.
Next time I use a cabinet I will look for better quality. It's working great but it's really cheap particle board.
