Removing chlorine

[crafty john]

All this talk about removing chlorine from tap water for brewing, I keep fish and when I do a water change I just leave the water to stand for 24 hours and then it is safe for the fish, so sense says that if you fill a sanitised FV with tap water, snap the lid on and fit an airlock, leave for 24 hours to allow the chlorine gasses to escape, this has to be a more natural way to remove the chlorine from tap water?

I keep fish as well . . . and filter my water to remove chlorine . . . I am not comfortable with the leave it to stand method . . . I posted some information here on the half lives of Chlorine following treatment methods

which is quite clear to me that just leaving it to sit for 24 hours is not going to get rid of enough . . . and certainly not chloramine . . . and most definitely not with a lid on . . . the gas needs to escape

Hi Aleman
That certainly told me intresting stuff so campden tablets work best then?

[crafty john]

It's not natural to find large amounts of Chlroine/Chloramines in water but if you want a natural way to remove them and activated carbon granual filter works well.

OK Ta

I also keep fish (is there a weird beer and fish synergy here?) and along the same lines I was wondering whether a campden tablet would be suitable for conditioning the water destined for the aquarium. Would the campden tablet introduce any fish unfriendly chemicals? Obviously I would still leave the water to stand for a while before using it.

I agree mate, better safe than sorry

There is an article in the next Brewers contact that shows whats left after treatment with a campden tablet . . . and assuming treating 20 US Gallons of Water containing 3ppm of chloramine then all the metabisulphite is converted to chloride and sulphate . . . My worry would be the residual sulphite if the chlorine was less than this. . . . . although it should gas off . . . say using an airpump and stone . . . I use a carbon filter

why the effort? Would you actually be able to taste the difference? Given time, chlorine simply degrades into salt. I've never noticed a side-effect from chlorinated tap water.

Chlorine reacts with phenols in the malt and hops to form chlorophenols that produces the classic homebrewed TCP flavour.

Agreed. My 1st few AG's had a TCP like taste, which I am now certain was due to chlorine in the water. Never had a problem since I started treating with campden tablets.

Just add half a camden tab and boil the chlorine off

[rick_huggins]

Some water companies use chloramines, these can't be boiled off. Although adding a campden tablet negates the need for boiling.

Double insurance then, love the odds without getting too scientific..
