I can't figure out a way to seal up the band around the lid. I have white life forming on my beers if I ferment in primary longer than ten days. So far it actually hasn't imparted any discernable off flavors. All I can think to use is cpvc cement, as it is the only adhesive I know of that's non-toxic. At high krausen the beer foams up to this level, so my thought is that silicone would be bad... what's everyone doing? And also, what about the threading in the lids?
...from the very shallows of my mind, for had their been any depth, this could all have been avoided
