I believe I remember a discussion that trichlor pucks are fine for long term storage (like over the winter), but how about calhypo? My bucket of trichlor pucks included many desicant packets, but there's nothing in the calhypo bucket to prevent moisture absorption. If I buy a big bucket now, will it be fine next year? It will be stored in a shed, so it will see freezing temps in the winter and temps around 100-110 deg F during the summer.
