first reef, is tapwater safe in a starter nano?

Believe half of what you hear on RC... Yes, calgary has some occasional (usually spring and after a big rain) water quality problems, but nowhere near like the problems they have in most US (and shall we say eastern ontario) centers.

Calgary water's perfectly fine for use as your base water. Yes, as you advance, you'll eventually start wanting RO for SPS, and to use some of the other formulations of salt which require RO. But for now, use tap water, learn the basics then you can start heading down that path.
