Hypothetical question

I would also add that an oxydator changes more than O2. I expect that, like all oxidizer additions, trace element bioavailibility is altered. Not say that is good or bad, but it is going to happen.

The hydrogen quickly breaks down as it leaves the Oxydator. A guy did some testing of free peroxide using an Oxydator but could find none using an Oxydator. I would also contest that an Oxydator is safer than using ozone and that the probability of any negative effect on trace elemebts is no more than ozone. However, without labority testing then it's just conjecture.
I have yet to witness any negative effect on any of my aquariums in all the years I have been using them. Would be great if some real laboratory testing could be done on the use of Oxydators.

I agree that ozone will have the same sort of effects. It has lots of effects, some good and some not.

No hydrogen peroxide needs to leave to oxydator to change the speciation of trace elements that are entering it and leaving it.

Hydrogen peroxide does indeed leave the Oxydator however, most is broken down as it makes it's way from the plexiglass container as it comes into contact with the inside of the ceramic beaker. There is a small gap between the container and the beakers side The beaker appears to be made of the same ceramic as the catalysts, I can't confirm that but it's likely.
I currently use 12% peroxide with 2 catalysts in my model A and my 138 US gallon reef tank.

Yeah, the idea as I understand it is that evolution was permitted to explore large insect body sizes while oxygen levels were low, not that insects just inevitably got larger at high O2. (The tracheal respiratory system apparently doesnt scale well with body size at low O2)

You may need to maintain the elevated O2 for geological time scales to see an effect

Sounds like a good experiment. Better start now.
