Call me skeptical, but it seems to be just an air pump with a diffuser that creates much smaller bubbles. If the electrolysis is taking place in the diffuser then it would need a source of electricity, the only power I see goes to the pump.
Regardless of that, there’s only so much oxygen that water can hold. The size of the bubbles should be irrelevant, the amount of oxygen in the bubbles is dependent on the power of the air pump and the size of the hose.
Electrolysis involving water isn’t usually a good thing. Think iron corrosion in water.
I’m going to do some more research on this, but it seems like pseudo science, and the company only offers proof from a single user of their product, and those results are subjective, a 20% Increase isn’t enough to convince me.
I’ll be curious if you notice any difference @SWSVIC.
Also, if the hydrogen atoms are separated from the oxygen atom and expelled then the result is no longer water. It’s been awhile since I’ve studied chemistry, but if the oxygen atom were to remain as a dissolved atom it would need to bind with something else or else it would become a normal air bubble.
