hydrogen peroxide to remove chlorine

  • We are currently upgrading MFK. thanks! -neo
I just spoke with a research doctor at Harvard Medical. He said while the H2O2 would remove Cl he would not recommend it. For one, the H2O2 you buy in the store is not pure, and is practically impossible to obtain. This research doctor has kept freshwater and saltwater fish, so he has knowledge on hobby in case anyone was questioning his creditably. I would be really interested in finding out what aquarium companies use to treat Cl in their products...Actually, it would probably make me rather upset, since it probably is the same thing!:ROFL:

sodium thiosulfate


Chlorine at high concentrations is toxic to fish; at lower concentrations, it stresses fish by damaging their gills. Concentrations of as little as 0.2-0.3 ppm kill most fish fairly rapidly. To prevent stress, concentrations as low as 0.003 ppm may be required. Fortunately, chlorine can easily be removed from water by the chemical sodium thiosulfate, readily available at fish stores under various brands. Sodium thiosulfate neutralizes chlorine instantly. Note that there are many ``water treatment'' products that are advertised as ``making tap water safe''. Read labels carefully. Inevitably, the ones that neutralize chlorine all contain sodium thiosulfate, plus other substances that may or may not be useful. If your water only contains chlorine (as opposed to chloramine), sodium thiosulfate is all you need. The most cost-effective treatments use only 1 drop per gallon of water. Most other water treatments are much more expensive in the long-term; they may require a teaspoon of treatment (or more) per gallon!

So I could just go buy 2 lbs of sodium thiosulfate and mix it up like it says and treat my water with it instead of buying products from the store? Thanks.

1) i am not a chemist.....please check with a pro.

however......my understanding is that to remove chlorine and NOT CHLORAMINES sodium thiosulfate is all that is needed.

its is pretty cheap.........PLEASE GOOGLE TO FIND THE EXACT DOSE !!!! it is a white powder.... mixed with water you then use this solution to treat the water.....

2) I bought some to remove chlorine after bleaching my filter bags and filter cartridges.

hope this info helps

ps from the net

"""Treatment of tap water requires between 0.1 grams and 0.3 grams of pentahydrated (crystalline) sodium thiosulfate per 10 liters of water. """

please double check !!!!!!!!!!!!!!!!!!!!

hmmmm
will peroxide help fish wounds too?
:ROFL: :ROFL: :ROFL:

ya no one said anything about that one.
ive heard if left outside for a while but 24hrs?

np, no harm done.

i also would think that sitting out buckets, uncirculated would cause stagnet water.

Me too. But I also want to know, what happens to the chlorine molecule? I am assuming it can't just dissapear, but I am no chemist.

Peroxide will not remain regardless of whether or not it finds a molecule to oxidize and bind to or not it is simply water with one additional hydrogen atom and simply reverts back to Natural pure oxygenated water in most concentrations readily available it will not harm the majority of fish if used as a dechlorinator,algea stopper or simply to add more oxygen to the water( I have to honestly say that I've never quite heard it used in that fashion as an oxygenator but it will however accomplish that very thing)it is quite safe i assure you ...of course thos statement is somewhat anecdotal seeing as how I keep fish who seem to not react to it at all and the general science and chemistry around the substance dictates that it won't harm the majority of aquarium inhabitants but as soon as someone latches onto this as complete ans utter fact sure as I'm sitting here right now it'll wipe their whole tank out so proceed at your own risk and certainly know that there are certain fish that are known to be sensitive to peroxide in the water but in let's say 90% of all cases 95 maybe even there's no issue at all

I don't know if this is a good answer to the guys original post or not because I know nothing of the subject. But I do know that your reply is 11 years late!!

Wait.. lets market this and become rich. You could sell it as bottled oxygen for aquatic livestock at $10 an oz. Some poor schmuk would buy it!!
 
Honestly though, would you be able to rapidly recover from a Co2 crash by simply adding hydrogen peroxide to your tank?
