I am looking to start crash-cooling my beers and possibly adding gelatin if needed in order to start getting better clarity. I was thinking of just taking out the air lock and drilled stopper, and replacing with a sanitized non-drilled rubber stopper. Has anyone done this? It seems appropriate since no gas will be going out, but will instead be sucking in. I am just concerned that the internal suction could cause the carboy to possibly "implode" if it gets strong enough. If anyone with experience has any insight, it would be greatly appreciated!
