This is certainly a decades old problem that we all have encounter, but I am curious what people do to keep their boxed salt dry and not turning into a solid rock. I personally transfer my box salt into a thick bag inside a 5 gallon bucket that has a screw top. I twist the bag close, tucking its top down to keep it from turning loose and then close the bucket's top as tight I can, to the point I know I still can open it without being a 2 man job. And...it still gets rock hard every once awhile from air moisture. Its very frustrating, having to fight with it in order to measure it when needing to do a water change.
I have thought about trying a Gamma Seal top, not sure if it would make much difference.
I, also, thought about trying packets of silicate air moisture absorber in the bucket, not sure if those work faster than the salt itself.
