Makes sense. FWIW our system for the house has a hydrogen peroxide pump right before the filter that is there to help with the oxidation. It quit working a couple months after it was installed. The water in the house is still clear and smells fine without it so just leaving it "broken" for now. The peroxide is like $25+ per gallon so if we can get along without it.......
I'm thinking hydrogen peroxide wouldn't work for you anyway as it kills all bacteria and that might make your biofilters a little unhappy!.
