Homebrew PCBs

Howdy

I have this "hare-brained" idea on another method to regenerate Cuperic Chloride etchant.  I plan on getting some "Oxygen Tablets" (used in fish tanks, live bait tanks, etc), and placing one of the tablets in a closed container of water to generate oxygen.  
The container will be connected via a tube to my bubbler, rather than my air pump. As a result, pure oxygen will be bubbled, rather than air.  I'm guessing that it should be as fast a regenerator as Hydrogen Peroxide . . . and not any more expensive when compared to 30 or 40 volume Hydrogen Peroxide - plus the etchant will not be diluted.
Any comments ? Has anyone tried this?  I'll post my results
