Small Update: added 5 discus. I've had them for about 2 1/2 weeks now and so far so good. Eating everything I throw at them from blood worms to pellets.
The tank is doing fantastic. I've got the lights down to only 35% power and diatoms have finally started to back off. No other algae issues. Plants are growing like weeds, the entire background has been covered and I need to do an intense trimming that I've been holding off. Once I get a chance to hack everything back a bit, I'll post a new full tank shot.
Picture of 4 of the 5 discus. Ended up with a Blue diamond, 2 galaxy turquoise, 1 leopard, and a cobalt that didn't make it into the picture.
