I tackled the aquascaping today. The goal was to pull the rock away from the side glass to both improve flow and allow me to clean the glass along the side. I also moved the Koralia 1 to the top left of the tank, although it is very visible now it gives more options for flow.
Aquascaping is even more challenging when you already have some corals in place. I will study this new configuration for a few days. I will have to move a few corals. For example I am thinking of moving the GSP onto an "island" in the sand at the front of the tank. That will allow it to expand but keep it under check.
I like watching the pulsing xenia, and this stuff really pulses, but I now have an appreciation for what others have said about it's rapid spread. I will have to limit it to a single rock or allow it to climb the back wall. I have reconfigured it's primary colony to give it contact with the back wall.
Here are photos from this afternoon's aquascaping:
