how to get dechlorinated water

[fish&chips]

what is the best way to dechlorinated tap water

water treatment .'
can leaveing it to settle for days help

pls let me know i dont really understand how you can dechlorinat water straight from tap to tank

 

[Dman]

U either have a water conditioner to neutralize the chlorine in the water or let ur tap water sit out for 24-36 hours to let all chlorine avaporate from the water (Garenteed to work)

I always have a few buckets of water dechlorinated sitting outside ready for an emergency. However I use the natural method. For some reason I prefer this to using unessary chemicals

 

[fish&chips]

thanks guys ive been leaving it in a bucket for 2 days then bottle for 3 so 5 in total will that do ?

should i then NOT treat the water as i did both

 

[Kossy]

Umm make sure the bottle is unscrewed its fine though just leave your bucket out for one day not two. You don't need two days

If you want to remove the chlorine from water without adding a dechlorinator it will probably take longer than one day of standing unless you add an airstone connected to a small pump. This is because the chlorine comes out of the water as the surface is exposed to air. By moving the surface of the water with an airstone more water is exposed to the air and so the chlorine is removed faster.

But why take chances doing things this way? Dechlorinator drops are very inexpensive and are readily available. One bottle lasts for a very long time. Chlorine is a deadly poison, do you really want to take a chance that it is not completely gone when you add it to your tank? Isn't it better to be safe than sorry when it is such a simple thing to do?

inch worm and all others pls pls pls
cheek out my thread on chlorine and chloramine

pls take a view its very important
and thanks inch m8
ive spent past 2 days cheeking out water wots in it why wot it does so on
im ringing my local water surplyer on monday to find out if the put
chloramine in the water as this is now surposed to be in water NOT CHLORINE
chloramine is a better thing for drinking water but not fish
confusio0nnnnnn

Chloramine (bound chlorine), it doesn't help to let water be in canister couple days, because clorine doesn't go away. And if you have chlorine in water, you need to pump air through water - it helps chlorine go away.

You can use either commercial water treatments or go to nearest pharmacy and buy sodiumthiosulfate (Na2S2O3). Those commercial water treatments contain same stuff. And if you have chloramine, thiosulfate doesn't remove ammonia - or in acidic water, ammonium -ion.

wot do you mean that chlorine wont go from water by leaing it

yes it does if left in bottle with the lid off or in a bucket much better in the sun
chlorine evaporates

Because chlorine is bound as chloro-amine = chloramine. And when it's bound, it means that chorine isn't free in water. And when it isn't free, it doesn't evaporate either. It still evaporate, but much slower than free chlorine. It takes couple weeks to evaporate chlorine from water when it's bound and water is just in canister (not circulating etc..).

Pumping air through water (airpump + stone) helps chlorine to evaporate, because "changing gases" happens on the surface of water. So not only leaving water to stay help - it's slow process - but circulating water helps alot. However, only few of us have time or room to keep hundrets of liters of water in canisters at home So, it's much easier to buy natriumthiosulfate or commercial water conditioners.

hmmm nice post

but not all chlorine is bound (i think)to the chloramine

chloramine is a compound made from 1 part amonia 5 parts nitrite =chloramine

now not all water has chloramine meaning that the chlorine cant be bound it is free and floting in the water by leaving it 24 hur makes it disaper

as many other would agree with

but chloramine can still remain in the water for up to 1 week

but the other problem being ...amonia from fish waste is in your tank (maybe example ) then you add your water had no CHLORAMINE but does have chlorine

you add this and would be mixing amonia from the tank waste and chlorine if not completly got rid of

which can then mix creating the compound chloramine ??

Only your water plant knows what they add into water Our water plant doesn't add free chlorine, only chloramine.

Still, chloramine dissociates and there is chlorine/chloride in water.

Hmm.. Where is chlorine, Cl2? NH3 + NO2- is probably something else than chloramine...

now not all water has chloramine meaning that the chlorine cant be bound it is free and floting in the water by leaving it 24 hur makes it disaper

Our water plant made a test. They put water in a glass and left it alone. After 11 days there was chlorine 0,03mg/l (from 0,33 mg/l). So it's quite slow process. Bound chlorine has slow reactivity.

but the other problem being ...amonia from fish waste is in your tank (maybe example

It's simple chemical fact that, if your water is acidic then there cannot be NH3. Ammonia has changed into ammonium -ion, NH4+. It isn't so harmful as NH3 and nitrification bacteria use it as food like plants use it like nutrient, so it's simply disappear from water. If your water is basic, then they can be ammonia in water - which makes ammonia test important for people who has pH over 7. Better way is to check first from your water plant, how much do they add chloramine into water and check it from your tap water too. If there isn't lot of it, you can "safely" change water. Bacteria use it quickly.

you add this and would be mixing amonia from the tank waste and chlorine if not completly got rid of

Maybe not

If there is ammonia in your tank, there is something wrong: there aren't bacteria enough, or they have died(?) or filtration doens't work, too much food, too much fishes... Ammonia as nitrite levels must be 0,0 mg/l if you are going to keep fishes in that tank.
