weird, never heard of this. it's doubtful i would try it. lol



Does hydrogen peroxide remove chlorine? Hydrogen peroxide can be used for dechlorination, in other words to remove residual chlorine. Residual chlorine forms corrosive acids when it is oxidised by air or condensates on process systems.
When chlorine reacts with hydrogen peroxide, hydrogen peroxide falls apart into water and oxygen. Chlorine gas hydrolyses into hypochlorous acid (HOCl), which subsequently ionises into hypochlorite ions (OCl).
Cl2 + HOCl + H+ + Cl
HOCl + H+ + Cl


After tha, hydrogen peroxide reacts with hypochlorite:
OCl- + H2O2 (g) -> Cl- + H2O + O2

The reaction between hydrogen peroxide and hypochlorite takes place very quickly. Other organic and inorganic substances cannot react with hypochlorite.:grinno: :grinno: :grinno: :grinno: :grinno:

What if you use to much H2o2? If there isn't sufficient chlorine to react with the peroxide, what happens? Is H2O2 harmful to fish?

i would think so but not as bad as chlorine.... as for me i will use aquarium safe products.........john

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.
 
i also am not a chemist however.....my 2 cents

the first get together form HOCL whihch is a acid the HOCL the reacts again with the h202 again..... and now I ASSUME the cl is somehow locked up but i will ask around and see if anyone knows.....

i dont know if that helps at all or just restated your question....
