Toronto tap water - let sit or use conditioner?
I live in Toronto. I have read that the city uses Chloramine to treat its water. I am afraid this will be harmful for fish if not treated with chlorinator conditioner?
Those of you who live within Toronto border, have you used tap water and just let it sit for x number of hours before? If so how many hours are safe enough?
I am looking to set up a guppy tank.
