It was my understanding that it is bad, in particular if you're growing "organically" to use fresh tap water that contains chlorine (or chloramine).
If you look around, you will come across countless posts where people recommend to keep water sitting out for 24hrs to let the chlorine evaporate.
The idea here is of course that the chlorine (or chloramine) is bad for the micro organisms in the soil.
Now I come across several interesting articles like
A Guide for Using Tap Water in Your Garden - The Grow Network : The Grow Network
where they BASICALLY say that chlorine, while possibly not "optimal", is not really harmful because IF AT ALL, it would only hurt micro organisms 1/2" down into the soil, there where (when you grow outdoors) micro organisms would be killed anyway by heat and sun.
I also read that the typical soil contains so many micro organisms which multiply so fast that cholorine in tap water is really a total non-issue. Tests have been made trying to kill the organisms but even with watering every day with lots of chlorine in the water, the micro organisms were thriving.
What I would like would be NOT just people commenting with the usual "hear say" and echoing what they read elsewhere, but actual EXPERIENCES of people who use (hard) tap water that has chlorine in it and whether it made any difference to have water sitting out, or just water straight from the tap.

There are ways to dechlorinate tap water, some recommend H202 and others Vitamin C. One person mentioned a VERY TINY amount of 1-2 drops (!) H2O2 per gallon of water would be sufficient to get rid of all the chlorine.
My question here is...if the idea is to make the water "more suitable for micro organisms", then wouldn't the H202 do more harm than good...or is such a tiny amount like 2 drops of 3% H2O2 solution so little that it would indeed get rid of all the chlorine...but have no effect whatsoever on microorganisms?
--> in case you wonder why I even ask all this....in previous seasons I always kept buckets of water outside over night "to let the chlorine evaporate", but it sort-of becomes a pain in the ass, especially outdoors where it is MUCH easier to just take the hose when I want to water. I really wondering whether all this "let the chlorine evaporate" is just an urban myth and whether I would be as well off watering straight from the hose, ALSO when I want to grow organically.
** Related 2: When I take a bucket up on the balcony and fill it with the nozzle set to a fine mist/spray, you can literally smell the chlorine. Is it possible that filling a bucket that way would already get rid of lots of chlorine, seeing that chlorine is a gas?
