Thanks for the compliments. The foam backing was a test for the reef system. What I like about it is the look and that stuff will grow on it. What I don't like is how boyant it is! I had originally planned to spray it on the walls of the reef, but at the time I was also planning a closed loop system. Now I am not. But I will use it on the rock structure support.
Finish for the viewing panel is still being debated. I am partial to light woods and may do the wall in maple, bamboo, or some other light colored wood. We could get away with stone based on our NW location, but I am concerned about it being a too "bulky" look. I am toying with the idea of using the 8" window sill as the base for a bar with stools.
I haven't really thought it through since before the great reef idea, this was going to be the location of an LCD TV surrounded by book shelves etc. I have been looking at a lot of other big tank walls and I really like the clean spartan look that allows the reef to "pop", thus another reason why I probably won't do something with stone. The only thing that seems to be decided is that along the opposite wall which is mostly windows we will build in a 20' long bench seat that allows us to store our aikido mats inside.
I am contemplating the easy chair route, as well as the poker table route. Maybe I could train fish to read cards???
First things first....
