Will, there is such a thing as Professional Strength Melafix, which is 5 times more concentrated, so quicker to dose for large volumes, and is used for convenience by people in the fish trade. I don't know where or if you could get it in Canada, though - I'm UK-based.
Laboratory studies show no evidence of any ill-effects of Melafix on scaleless fishes, or on invertebrates.
