Hi,

Anybody has more info on hydrogen peroxide use in aquariums? i'm really interested on how it can be used to increase oxygen content in water, specially during brownouts. i'd like to know how to use it, and the dosage require?. more info pls.

thanks.
 
I've never heard of it used in general aquaria. It may run the risk of it. Person to ask is Rockabillychick. she's used it before.
 
Hydrogen peroxide (H2O3) can be used to increase oxygen levels in emergencies dose as follows
1drop per bag max.for transporting
25ml per 100litres for aquarium usage

CAUTION
This is a one time treatment or your fish will suffer gill damage and really should be used in emergencies

Hydrogen Peroxide is H2O2...hence the name. I do not believe it would cause gill damage unless you added an extremely large amount. When added to water it almost instantly becomes water and oxygen so repeating this procedure makes no difference.

It almost certainly does not "instantly" turn into water and oxygen.
After all the hydrogen peroxide you can usually buy is diluted (with water) H2O2.

H2O2 is a very strong oxidizer - but what concentrations would be necessary to cause gill damage ? No idea.
I know people use H2O2 to treat algae problems in their tanks. When not careful enough these people reported killing fish and shrimp.

In a chemistry lab, I once poured accidentally some 30% hydrogen peroxide solution over my hand. My hand turned completely white and hurt like hell. I'd keep it out of my aquarium. In a very low dose, I use it for cleaning all residual algae from the reactors and aquariums where I grow cyanobacteria at work; after the culture is out ;).

Wrong! It almost instantly become oxygen and water when added to an aquarium. This is due to a larger surface area and exposure to the atmosphere. In the bottle it has a very small surface area and normally a cap to close the bottle. When poured in to a source of water that has a large surface area exposed to the atmosphere a violent and almost immediate reaction occurs. That is why on the bottle is say to always keep the cap on. If it were exposed to the atmosphere long enough it would turn in to H2O.

It's not wrong. But I suppose your differences lie in the point that you disregard the time scale. For the initial minutes (depending on the concentration), hydrogen peroxide will perform it's highly destructive oxidizing power. That's why I mentioned that I use it - in very dilute form - for cleaning a water-filled reactor. It will oxidize all organic particles it comes in contact with.
