How long does it take for chlorine to evaporate in a bucket of tap water?
Question:Don't want to water my plants with chlorinated water, so I filled a bucket, how long do I have to wait before the water is chlorine free?thanks
Answers:
In full sunlight, if it's unstabilized or combined chlorine, then it will take only a few hours as chlorine is UV sensitive.
The best and easiest way to rid yourself of chlorine in tap water is with sodium thiosulfate which you can get at any pet store that deals with aquariums. This is a relatively inexpensive chemical that only takes a few drops to get rid of chlorine, depending on how much is in the water.
It takes about 24 hrs. I use it for my fish and they do just fine.
Let it sit overnight. I always do that when watering my orchids and other indoor plants.
To really answer this question, you need to know if your water source used chlorine or chloramine, which is a nitrate of chlorine or something like that. Chlorine evaporates out in 24 to 48 hours, but the more deadly chloramine take a month to break down. Use a dechlorinator from the pet or pond shop to remove this toxin. Municipal water systems have had to go to this strong toxin to combat the resistance in the water-born bacteria.
