also remember Calgary has very hard water to start with, get a water report for your area and see what kinds of chemicles/elements are in it, take that number and tripple it and decide if you want that in your tank. remember thoes meters you are thinking of won't tell you what makes up the TDS only what the final number is.
also there are several water quality reports from lakes that might have the type of fish you have you can look at to compare. I find people do everything they can to get the perfect water quality for there salt water thanks but then just use tap water and not worry about it with there fresh water tanks, water quality is just as important for one as the other.
