Hello Everyone,

I bought an Oxydator mini for my 10 gallon TB tank and it came with the 6% hydrogen peroxide solution. I am at the phase where the solution is running out. I bought 12% food grade h2o2.

I was wondering if anyone has used the 12% without diluting for their oxydator and had no bad side effects?
or

If they did any experiment and what highest % of h2o2 that can go into the oxydator mini without bad side effects for the shrimps?

Honestly i would not go higher than the 6% solely because it came like that or is instructed to be used like that.

Oxydator works on a simple principle - catalyst speeds up the natural decomposition of hydrogen peroxide to water and oxygen - these are the tiny bubbles you can see in the bottle. Accumulated oxygen pushes hydrogen peroxide out from the bottle, where it reacts with the ceramic bowl - releasing pure oxygen and water into the tank (this usually can't be seen as oxygen dissolves into the tank water almost instantly). Higher concentration of H2O2 means higher rate of released oxygen in the bottle and into the tank. 12% is probably safe to use if you won't spill it in the tank directly, but one bottle won't last as long as with 6%. Also be more careful while handling 12% as even 6% can "burn" the skin.

Personally I use 6% H2O2 and rather increase number of catalysts if I want more released hydrogen peroxide/oxygen. If you want one bottle to last longer, use lower concentrations of hydrogen peroxide - mini Oxydators used to come with 3% or 4.5% in the past (if my memory serves me well), so these concentrations will work fine.

Going above 12% is probably too risky and frankly, I don't see any point in doing it.

Do these things really make a difference?

In extreme situations (like fish gasping for oxygen at the surface in the morning), definitely yes. Otherwise..probably not really needed. I take it as a good and quite cheap way how to easily increase the amount of oxygen in the water, especially during summer heats. Or if one doesn't use the ceramics bowl, Oxydator can be used for a constant low dose of hydrogen peroxide into the tank water directly.
