An hour? I still move rocks. Never happy.
Scape for water flow and detrious suspension. Don't need to scape to peninsula design, can scape like a normal tank. That window may pose an algae problem. Not so much the patio door because it looks like it gets planty of shade and the overflow but the window behind tank. But it will also allow you to have lights come on much later in the day than those whose homes are dark. Pretty sure that window has some type of Uv filtration. Get lots of snails.
