Do you believe "low oxygen"events causes fungal outbreaks in RDWC DWC?

Just so we are all on the same page and have a clear understanding of what you are trying to say and what you really mean…

What exactly is your definition of “oxygen enrichment?”
Any added dissolved o2 is enrichment. It doesn't matter where it comes from.

If you guys want to build your own electrolysis equipment you can find the iridium cathode/anode assemblies on alibaba. Then you just need a switch mode dc power supply.

Or you can just use an ozone generator since ozone dissolves much more readily into water and it decays into o2 with the added benefit of killing biologics. That would be ok if you weren't adding beneficial bacteria to your nute res., I'm guessing that a lot of us do add beneficials to our res. In which case ozone is bad and all water electrolysis produces ozone.

Air, a normal atmosphere contains between 20.8 and 21 percent oxygen, OSHA defines as oxygen deficient any atmosphere that contains less than 19.5 percent oxygen, and as oxygen enriched, any atmosphere that contains more than 22 percent.
PSA O2 Generator, VSA O2 Generator, Compressed oxygen, liquid oxygen,O2 Grow electrolysis.. you right about O3, it's an excellent disinfectant, kills microbes and bad odors, but it a very poor method if your interest is oxygenation (O2)... O3 is unstable with a very short half life.
If the plants and microbes are important and need more oxygen, give them more oxygen... that's only logical.
*Here's the big question: How do you know if your plants and microbes really need more oxygen?
Most people know when they see root rot symptoms and by then it's way to late.

I'd like to see independent blind studies of your product with respect to OBSERVED DO levels in a traditional aeration technique at various temperatures. I'm thinking you don't have this. Not hydrolysis in general - but YOUR product.

Everything you're stating is theoretical but not ACTUAL product data.

Smoke and Mirrors...

Specifically what product would you like to see?

they had a write up in High Times. does that count? lol. that J Henry's company paid for. and they still can't sell this crap.

because in theory it "should" be better but it isn't. if it was, there would be side by side grows showing how much better it works. and his company could afford to pay for advertising here instead of random ad placements by Ms Henry.

Ok I'll play your game.

"The relative amount of O3 produced (relative to molecular oxygen) depends on the overpotential, pH, radicals present and anode material. O2 evolution is greater than that for O3 due to the lower potential required. At low overpotentials, very little O3 may be produced but at high current densities and overpotential, up to a sixth (or more) of the oxidized molecules may be O3. As O3 is more much more soluble than O2, there may twice the dissolved O3 than O2 but the bubble gas will contain about 20 times the O2 than O3"

So yeah.... got anything else besides Wikipedia?

Answer the question: How do you maintain an O2 supersaturated H20 solution at atmospheric pressure and average room temperatures?
One way of supersaturating water with O2, is counter-intuitive.
Add a large planted aquarium to your reservoir system, then add CO2 to the water during lights on period. The plants 'exhale oxygen during photosynthesis' this pushes O2 saturation to above atmospheric equilibrium.
