My earlier post also says to boil. Don't get enough sun in he UK for it to de-chlorinate water. Would take 6 months.....lol ☺I have always boiled my water for misting and drinking with no issues. I keep tropical fish too but use a "tap safe" type additive for that as don't want to be boiling and cooling 40 litres of water every week.@Thistles: Yeah that's why I agree to use bottled spring water or something that is free & clear of chemicals.
@leaveittoweaver: If you don't have the extra cash to go buy water, then boiling it is probably the best bet. If not, I would try the water in the jug trick. Anything you do to help get rid of any (if not all) chemicals in the water is extremely helpful. . I'm sure the T's will appreciate it as well.
