Anyone using one of these?

We have a <"few threads"> mentioning them. They had a vogue with Rift Lake Cichlid keepers about 25 years ago, but like a lot of these things it didn't last people were soon onto something new.Anyone using one of these?
It would really be what @mort says. People would look at a coral reef, or the surge zone of a Rift Valley Lake, and says this is an alkaline, high oxidising environment with very low levels of nutrients and DOC. This is true, but it is only <"part of the story">.I used it with the seahorses because they are very susceptible to bacterial infections and common advice was they needed it to survive (if was also advised the most sterile tank you could make which I learnt was not necessary at all, in fact quite the opposite).
I quite like using them, but I wouldn't say they make that much difference, if any
This did have me wondering as they seem to be prevalent in the shrimp world.It isn't snake oil, but there are other ways of achieving high oxygen levels.

That is what they are doing, the extra oxygen comes from the break down of the hydrogen peroxide (H2O2).Are these simply turning Hydrogen peroxide into water and oxygen and just oxygenating the water or are they doing anything else?
Yes, more oxygen raises the ORP.adjusting ORP but that is just by higher levels of oxygenation?
I assume that the idea behind the ceramic catalyst is to ensure the reaction occurs where you want it, and that only H2O and O2 end up in the tank.but I am assuming these things are powered by H2O2 but only release H2O and O into the tank?
So expensive high tech airstones thenHi all, That is what they are doing, the extra oxygen comes from the break down of the hydrogen peroxide (H2O2).
I'm not sure, I think titanium would do. It is "transition metals" that are the catalyst, and I assume that it is cheaper then silver. Platinum or palladium would presumably be the best options, but more expensive again. I assume one of the reasons for the ceramic is to control the reaction, it is potentially explosive.I was told by the UK importer at the time that both the Catalyst pellets and the pot contained a Titanium compound to initiate the reaction. They both appear to be made from the same dark brown ceramic.
The small bubbles and 100% oxygen (air is 21% oxygen) would make it more potentially efficient than an air stone, but I've no idea if there are actual figures for ORP using an oxydator or alternatives.So expensive high tech airstones then
