For long term use Ozone is better than H2O2, as for short term use in an emergency you can use stabilized H2O2 but Tech grade as in Hydroponics stores is better and food grade tops that but must be kept in the freezer.
"Food grade and Technical grade hydrogen peroxide are essentially the same. However, the FDA regulates among other things the processing of Food grade hydrogen peroxide.
For Example:
The manufacturer produces 10 drums of technical grade H2O2. He would test the first and the last drum for quality and purity. The FDA inspects or test all 10 drums. All 10 drums are now considered to be food grade H2O2 after the additives added by the manufacturer for compliance. If the packager pours food grade H2O2 out of one of those drums into a smaller container, it is no longer a "food grade" unless that smaller container is also tested for the FDA compliance." http://tinyurl.com/cq3zsk
H2O2 would also work, wonder how long to ozonate to achieve this?

How does H2O2 affect EIS?
When H2O2 is added to EIS (one or two drops per glass of EIS), it will be noted that there is an immediate clearing effect. The Tyndall (what you see if you shine a laser pointer though the liquid) will become very faint as well. If the ppm of the EIS is sufficiently high (25 to 30 ppm) a white cloudy precipitate may form as well.
There are a number of reactions that occur. H2O2 is normally thought of as an oxidizer, but it can act as a reducer as well. Also silver is considered a catalyst for H2O2, but in actuality gets directly involved in the reactions.
The H2O2 reacts with the silver particles, producing ionic silver, a combination of silver hydroxide and silver oxide. This makes the large particles disappear, reducing the tyndall. However H2O2 also reacts with the silver oxide and silver hydroxide producing a 2 atom colloid of silver plus oxygen (and water in the case of silver hydroxide). Over time this 2 atom colloidal particle can end up being converted back to silver oxide and silver hydroxide, and so forth. The final result is a mixture of ionic silver (hydroxide and oxide) and very small colloidal particles. Thus if you add H2O2 to freshly made EIS, you can sometimes see the oxygen bubble off, and the tyndall may change significantly. But more importantly, the particulate portion of the EIS will go from being medium or large particles to many more very small particles, and the particle content will increase from a typical 5-15% to around 30-50%. If you have a strong tyndall from large particles, it will decrease, and if you have a weak or no tyndall it will increase with the formation of the 2 atom particles. This enhances absorption, as well as effectiveness. Note that it is recommended to let the EIS sit for 5 or more minutes if you do add H2O2 to it to let it stabilize.
One would think the guy would know the difference between Gold (Au) and Silver (Ag).
What ever the reaction is, or the effectiveness of the end product, I can tell you that a single drop of Hydrogen Peroxide will turn a bottle of colloidal silver completely colorless in just moments.
If all it took to turn large particle ionic silver or colloidal silver into tiny particle more effective silver was a drop or two of H2O2, I have to wonder why some companies have spent up to half a million dollars developing their processes, when all they had to do was make the most basic and inexpensive systems and add H2O2. Something does not seem right to me.
