the other thing that is constantly on my mind is how on earth I take the corals I have, and the rocks I have, and integrate them into a new layout. Unless I basically design new rock on the bottom and try to stack our existing rock on top, to as not to disturb corals too much. I asked my wife if she'd be open to a complete break down, sell off the current corals/livestock and start over and she said no, lol. I guess that's a good sign! She likes what we have built and collected so much she doesn't want to part with them and would rather integrate them into a new tank. It's nice to share the hobby together so much.
