The problem is how to split the hydrogen peroxide slowly. If you have canister filter substrate made of sintered glass, you may try how it reacts with H2O2. This is a hypothesis only, but if you have substrate, it costs you little to test how it works. The peat may do, too. H2O2 tends to degrade on porous materials.
An other possibility is to spit (yes, in earnest, I'm *not* making fun) to the flask with H2O2. The saliva contains enzymic matter that speeds up the catalysis of H202. I'm not sure if it works with killies, but costs nothing to test this method. The mouthwaters with H2O2 rely on it.
It is not difficult to start the reaction 2H202 -> 2H2O + O2. The difficulty is to control the reaction. If you use inorganic catalysts, like metal oxides, the reaction may be too vigorous.
Please tell if these suggestions work.
