If there is foam in the airlock, then it sounds more like blowoff then suckback. In which case, if it is heavy, remove the airlock, and replace it with a blowoff tube. Just plug a tube into the stopper and put the other end of the tube into a jar or glass of either water or sanitizer. Make sure to sanitize the tube before you plug it in, but this will act as an airlock while allowing any blowoff out without contaminating the airlock.
