my 180 gallons discus tank

Wow. Those are beautiful discus, especially the bright red-orange one. And I love the large school of cardinals. What kind of filtration, lighting, and substrate do you have on this tank?
 
What type of light hood do you have, Sure looks nice. Is it aftermarket or did it come with your tank? have you found it to put out enough watts for your plants? Thanks in advance.
ps> yes, my vote it is a dream tank for sure.
