Thank you all for the support.
After I brought home the aquarium and stand, it was time to aqua-scape. In past tanks, it was a struggle for me....I never achieved my desired aesthetics, plus stacking rocks not only made me paranoid but it also created poor water circulation. The goal was to have rock-work that was unique, stable and allowed ample water flow throughout. I clearly needed to attach the rocks to each other, but I was not keen on mortar products. Either they were specifically designed for aquariums but far to expensive or would leach lime, cement or other nasty elements into the water. ;Stop
After a little research, I decided to use pond foam. Completely safe for livestock, workable and slightly flexible - I felt like it was the ideal option. The only draw back was color, everything I found was black which is a stark contrast to the white-ish dry rock. However, corals and coraline algae should easily disguise differences in color and texture - I was okay with the temporary appearance. The nursery section of our local big box home improvement center had pond foam in a can for $5. :D
As a fisherman, I know that fish congregate around natural (or unnatural) changes in environment ie, where flats become vertical, shallow water meets a deep ledge or even oil rigs in the middle of open oceans. So the decision was to create an aqua-scape that mimicked the transition from the edge of reef to caves and overhangs. Edge of the reef was to provide high flow and limited rock work for SPS and open water fish, while the overhangs and caves were created for softies, LPS, shy fish and inverts.
With concept and materials in hand, it was time to get creative.
