What exactly are you trying to do?
A Mazzei 584 is venturi injector usually used a skimmers for a SW aquarium. They are designed to inject large amounts of air into a large amount of water. The bubbles created are comparatively fine, but noting close to what would come out of a true CO2 injector.
I don't think the Mazzei 584 would do much of a job injecting CO2 at something like 5 bubbles a sec into the water flowing through the injector.
