If I cannot buy bleach what makes this person think I can find the substances to make my own?

All would have been explained if you'd read the article. That jug of bleach in your laundry room has a shelf life of 6 months before it starts to lose effectiveness. The Pool Shock has a shelf life of 10 years. Pick up a pound of it at Wally World for $5 now before TSHTF. As in all prepping, you do it now or you become one of the hoards of zombies the rest of us will be guarding our homes against.

In my experience Walmart only carries a 43% concentration. Go to a pool store for the preferred 73%.

The pool shock at the local wally world doesn’t contain any calcium hypochlorite. Read the ingredients.
