Could this not be achieved by adding an airstone?
Just wanted to add, Thanks for sharing this video. Just love seeing how others around the world care for these magnificient little creatures. Makes me want to get some blue shrimp
Nahh, what this oxygenator is accomplishing is it makes pure O2 gas. The chemical reaction insures it is pure.
Airstones are great and they really help, I have two in my 30 gallon alone, they raise oxygen in the tank but also add in other gases from the atmosphere (eh is that the right word? I'm tempted to say atmosphere haha) which aren't as good as pure oxygen.
