What do you guys think of my new setup
 

I use to hang out here all the time learning but I was never in the nano forums since I had a 55 gal FOWLR. Well now I that my 55 has been running good for a little over a year now I have decided to set up a new tank and it is going to be a coral tank. So now on to the specs:

Tank: 20 gal long
Filter: HOB Aquaqclear 50 (for 20 - 50 gal aquariums 200gph)
Flow: 2 Aquaclear 30 power heads (175gph each)
Heating: 2 10 gal All Glass submergable heaters
Lighting: 1 24 inch T5, 1 30 inch T5, 3 Marina leds (for moon lighting)
Substrate: 40lbs of live sand
Rock: 17# but planing to get about a total of 30 pounds in the next 2 weeks

So that is pretty much my setup. what do you guys think about it. I got a steal on my 24 inch T5. The LFS I work at used it for about 2 days before the got a new MH on one of the display tanks. the 30 inch will be coming on the truck this week so I will have it on then. This is going to go in my bedroom and I allready have all the timers for the lights. Should I have the small T5 come on in the morning then both of them on around noon till ??? and then the leds come on for the night? As always all help and input is welcome. Thanks to everyone in advance.
