Water: Distilled vs purified vs everything else

[JoyAlbertMancini]

I just noticed someone mentioned leaving tap water out to stand or age for a few days. Does that work? I mean does it reduce the chemicals in the water?i live in belfast and our tap water is not soo good, even if we drink it we can taste a lot of chlorine kind of taste in it! At the minute im using bottled water, but because i have tetras and guppies and bettas i have tetra aquasafe hanging around so maybe the best thing is to treat frogs like fish when it comes to water! Also what does boiling the water actually do to it in terms of chemicals, if anything at all??

That only works if your water is only treated with chlorine. If it's treated with ammonia too then leaving it out to stand won't be as effective.

Thanks john, would it matter if it was aquasafe for goldfish or aquasafe for tropical fish?
