I dont believe that hydrogen peroxide could ever be harnessed to give slow oxygen release.

However calcium (and magnesium) peroxide (CaO2 - yes not the most stable compound) are regularly used to provide slow oxygen release in seed germination studies. I understand that the rate of oxygen release can be controlled with high levels of precision.

I have never heard of it being used in aquarium situations so anyone interested would need to research the topic.

Personally I have only ever used hydrogen peroxide as an emergency oxygen source during very hot weather and even then I am extremely cautious.

Just an old pathologist's ramblings...
