No a massive mode, but mine Grigg style is fed by a needle wheel pump (typically used for protein skimmers) on a closed look, so I just feed the CO2 into the gas input on the pump - ends up with nice small bubbles in the reactor. That being said, it is louder than just injecting directly into the reactor, so I may play with changing it. I also have a union at the top end (input) of my reactor, so I can take it off for cleaning or to bleed extra gas.
