Love the tank and the LED lighting. The wood is awesome. three suggestions however...would suggest a top for the tank. Discus can jump. You might need to dim your lights during the acclimation process. I see a lot of flow on the water surface and might need to reduce this if it creates a flow into the tank itself.
That's a cool LED floodlamp. I have the 10w version, great little lights! I was planning on using 4x of the 10w lights over my tank, almost the same as yours! But it's 60x30x24, instead of 60x24x30
