btw, number 69 is a waste of time stockpiling. Bleach does no keep very long. It has a limited shelf life.
Correct! One should store Calcium Hypochlorite (pool shock) make sure it only contains Calcium Hypochlorite only and no algeacides.
Calcium Hypochlorite is highly corosive. I place mine in its originial bag inside another tightly sealed bag and then in a empty plastic coffee can.
