I'm certain that is not how the oxydator works. It doesn't release pure o2. The peroxide is trapped in the container and the cataylst slowly breaks down the bond. The o2 being released inside the catalyst rises and expands putting pressure on the container and releases a continuous stream of peroxide into the aquarium. The peroxide oxidizes algae and organics giving you a cleaner tank. The positive consequence from the ongoing oxidizing happening in the tank is you have a higher concentration of o2 in the system.I would also go with an Oxydator over a dosing pump. Besides the other reasons mentioned, the way it actually works is different. You have to me more careful with direct dosing because the peroxide is an oxidizing agent. When this happens in the water column it can have unintended negative effects if the dose is too high.
With an Oxydator, you are getting the release of pure O2, but most of the reaction is happening inside the Oxydator, not the water column. This allows a safety margin, and the dose is a perfect constant trickle which is the most stable way to introduce it.
I do agree that there is a higher risk of overdose from a dosing pump and is something that really needs to be considered.
