Well that's the thing with the fizz factory. There is no way to regulate the flow, it shoots it all out at once with no air stone into a big 'ol bell diffuser (looks brutal). I didn't care for the system at all. Like Rex said, it probably will mess with your water chemistry if you drop it in the tank.
If I were you I would scrap those things and go get a juice bottle and start up a DIY system, make a vortex reactor or something and your in business. That's what I did (after buying the fizz factory) and haven't looked back since.
