my guess would be that once the pressure of the CO2 was taken out of the setup, all the crud was pushed back toward where the pressure WAS coming from. It took a pretty strong blast (more than 1 or 2 pounds from the bubbles) to blast it all out and open the way for the CO2.
The reactors move a fair amount of water, and if the check valve has any play at all (meaning it lets pressure push backward, it will allow crud to be pushed back into the airline inlet.
When I recharge a bottle, I always "clear the line" when I reconnect it. Just open it up and blast the blockages and detritus clear and then regulate it back down to your desired pressure/flow rate.
