What? 70 mg/l ??? No way. Last time I measured, I think I got a value of 400 (with the salt). I've never bothered to measure the freshwater by itself, hmmmm. Interesting experiment maybe?
Now, remember, there are two sources of water over here .... the Bow and the Elbow. I don't know what the Bow water is like (for the north part of the city), but, the Elbow is pretty much coming out of an old reef (limestone). That water is pretty hard, and is actually one of the reasons I went into reefing, instead of discus (which I really wanted to do at first instead), because I couldn't afford an RO at the time. So discus was outside of my means, but reefing wasn't! Weird, eh? Hmm, maybe not, I don't know.
