You don't need locals to chime in, lots of people in Calgary use tap water. It's fine, almost always. It's "what if" you need to think about. Or, you want the absolute best you can get and don't mind spending a couple hundred bucks. Can you run a reef without RO? Sure. Will it be fine forever? Ya, likely. Will something in the water kill all your corals one day? Could happen So you decide how much risk you're willing to go with.
