I am in the planning stages of an in-wall aquarium in a common wall between my office and family room. The idea is to have it flush on the family side and be maintained/viewable from office. I'm toying with the idea of adding privacy glass or smart tint to both the display sides so I can immediately frost one if not both panels giving either room or even the fish privacy. Anybody have constructive advice or experience they can share regarding privacy glass? Tank plan is 60x18x31 low-iron glass.
