Making H2O2

  1. Jun 13, 2009 #1
    Hello, this is my first post and i wanted to ask the following:

    How can you make H2O2 (hydrogenperoxide) yourself, because if saw in the store the other day a aquarium oxigizer (so your fish dont sufficate) wtch uses H2O2 in a percentage of 4.9%, but the stuff costs 5 bucks a bottle and only lasts a week or 3, so can i make my own?

    Thanks, wouternet

    I doubt you will be able to do it cheaper.

    This is not a physics question.

    And please use spellchecker.

    I always wondered how all the fish in the world's oceans, lakes, and rivers thrived to this day without oxygenizers and bubble thingies... ;-)

    Fact is, as long as the surface of the water is agitated ("wave" action) oxygen will enter it. You don't need any H2O2 gadgets and gizmos.

    And how agitated do you suppose the surface of the water in a fish tank is?

    Obviously enough.

    I am not using any artificial additives and in my tank fish doesn't have any problems. There is some motion of the water due to the filter pump, but even if I switch it off for few days nothing wrong happens.

    I did the same thing when I was training my fish to lie motionless, upside-down while holding their breath...

    Don't need no stinkin' oxygen!

    So I actually had trained my fish? And didn't need to flush them. Oh no!

    Sounds like a gimmick. Just use the air bubble pump. Cheap and has worked forever. Well, except in the case of my trained fish...

    H2O2 is a bit energetic. I don't think that O2 ends up in water that way. It is mainly dissolved.

    H2O2 might be toxic. So no extra training necessary.

    In the aquarium, H2O2 is used to kill algae and bacteria. It has been shown to be http://www.cababstractsplus.org/abstracts/Abstract.aspx?AcNo=20013101246", for example. It is likely that the peroxide rapidly reacts with any ammonia or amines present and forms reactive chloramines within a short time of the dosage. Chloramines, like Chloramine-T, have also been used as a treatment for various parasite and bacterial infections in fish, so it makes sense that a chemical that makes a chloramine in situ would be effective as well.

    It is NOT used to oxygenate water... but if used in high enough concentrations, it is useful as a training aid when training fish to hang upside down, motionless while holding their breath.
