Letter Re: Seeking Advice on Swimming Pool Chlorine for Treating Drinking Water
Mr. Rawles, I want to buy some pool chlorine crystals for long term storage. Holly Deyo’s book had a formula for purifying large amounts of water with this product, but how would I make a chlorine bleach substitute that could be used to purify smaller quantities of water or as laundry bleach? Is there an amount in grains or grams that could be used to make up, say, five gallons at a time? I know store bought laundry bleach like Clorox has a limited shelf life, so I wanted to be able to make [my own hypochlorite solution.] Thank you …
