Dechlorinating water

How do you do it?

You can put the water in a bucket and let it sit out with no top on for 48 hours.

Wouldn't most of it evaporate?

It doesn't all evaporate....Just save onto some milk jugs...and keep a supply and rotate...

Only a small amount will evaporate, especially if you keep it indoors(cooler). Also, if you "bubble" the water with an airpump, airline and an airstone, the process will go a lot faster (probably a few hours).
The principle is that the water gets heavily oxygenated as well as stirred up by the bubbles - allowing the chlorine to evaporate off and dissapate faster. In theory you could also stir it up (vigorousely), or, just pour it back and forth every now and then - it would have the same effect.

I have heard that often chloramine is used instead of or along side chlorine and that it doesn't evaporate. But i have never had a problem. I use distilled for seedlings and for cloning but other then that i just keep a 15 gallon container full of tap water sitting around, no problems yet. I have heard that you should avoid those aquarium drops as they convert the chlorine to salt or something like that.

You are absolutley right..chloramine and chlorine is in most tap water. The chloramine doesn't evaporate. My guess is that the chloramine is in such low doses that it doesn't affect things.(still doesn't make much sense because I've allways thought that any amount of it will kill bio life) I've posted threads before asking if pond dechlorinator would work..no body seems to think its a good idea(me neither really.. the active ingredient is Sodium Thiosulfate) I have been told that citric acid will do it....I'm 90% sure it was citric they said...either way they said vit. C has it.

Thing is, I'm using an organic plant tonic, and chlorine would kind of lower it's effectiveness. So I need most of it out.

maybe you should buy some distilled or get a RO filter system. That would do it im sure.

Chlorine is very volatile, so it will evaporate very quickly from your source water. If your water is only treated with chlorine, then letting it stand over night should allow the chlorine to evaporate from the water and make it safe to use. Or you can use an airstone to speed the process up. This will increase the surface area of the water and allow the chlorine to evaporate even faster.

Here's the catch. Some municipal water supplies have switched from using chlorine to using chloramine. Unlike chlorine, chloramine is non-volatile. It doesn't evaporate quickly. If your tap water is treated with chloramine, it is important that you get a dechlorinator that will neutralize chloramine. Check local pet shops. They should know if your water is treated with chloramine or not. A bottle of dechlorinator is only a few bucks.

hi. i have choramine in my tap water to. i tested it with my pool kit. i bought a pur water filter that atached to my fawcet. retested my water and there was no more chorine present. it cost me about $40.00 at homedepot and took 5 min to install.
