Thank you for the info. I put it on my list next time we drive near Wal-Mart. This seems to make much more sence than buying bleach. It helps to know how much pool shock to use. Thanks for your help. ~Lindy
You don't use bleach in your laundry? I like to use it for all whites, socks and underwear. I would still want it for doing laundry if the SHTF.
I know what "Shock" is but never considered it to "clean" water of bacteria, fungi and parasites for drinking.
