Here's the start of my attempt at a new structure for my tank. It's going to go in the back center, between my overflows. There is 14" between the overflows, and about 9" from the back wall to the back of my current islands, so I have a 9"x14" area to work with, and I'm planning on it being about 16" tall. Using Marco rocks and EMarco cement. The first attempt at using the emarco failed. I believe I had the mixture to dry. This time I had it a bit wetter, and I also wet the rocks.
This is about half of it. This is all I'm going to risk cementing till it dries fully, then I'll continue.
