Cube Aquascape Ideas?

My 100gallon marine tank is on a 2 month recycle due to ich parasite and fin rot fungus. I lost 5 fish within a week due to fin rot including my breeding pair of clownfish (had the female for 3 years was a hard blow to me ...)

So as I have nothing better to do I want to rescape my tank. The tank is a cube shape, so I'm very limited I do find that the rock work can look almost too big for the tank if you get me. I want a nice scape that will utilize space while also looking nice.

The tank has around 20+ corals in it ranging from SPS to Soft corals (full list: 2X acropora, 2X leather finger, 1x brain coral (large 6inch wide), 4X candy cane, 1X colt coral, 1X toadstool coral, 1X metallic green star polyps, 1X button polyps, numbes mushrooms - bulls eye, fuzzy etc, 1X goniopora, 1X gorgonia)

So while the scape may be pretty I also want it to be useful for holding corals especially for the SPS who require high lighting.

So any aquascape ideas you like please let me know, or even post links to cube aquascape pictures you like so I can get inspiration.

My yellow tang and my purple firefish are currently living in a 30gallon container for the next 2 months, they have a nice set up, both are eating hungrilly, both got freshwater baths before going in and both have hiding spots (no live rock as all my rock is contaminated at the moment)
