RO Water vs Tap Water (Edmonton)

[Snufflupagus]

I agree, test your water first and you could get away with it. I personally was using conditioned tap water in my first tank and things were ok, not perfect, but it worked fine. I've since moved to a RODI system in my new tank and life is much easier, I don't really have to worry about the water going into my tank. My opinion would be to go with the RODI system, your stress level alone is worth it.
