I have used drugstore H2O2 in an emergency as an oxygen source. It usually 
is only half the strength you quote (3%). I just add it to the fish water 
(in very tiny amounts). The lower concentration is more stable, I think, 
and may not work in their apparatus.

I don't have any idea what they use. Almost everything causes hydrogen 
peroxide to dissociate into water and O2 -- light, organic matter, 
inorganic salts or their ions, you name it. It is a notoriously unstable 
molecule, which is partially why it is such a powerful oxidizer. Perhaps 
one of our chemist friends can suggest something that would provide a 
slow, long-term release of O2. From my limited knowledge of chemistry, 
that sounds a bit improbable without elaborate pH, temp., tds, etc., controls.
