We all store liquid bleach along with our other prepping supplies. Liquid bleach is a powerful disinfectant and sanitizer and it has been used to purify water as well. But did you know that there is something better? Something with an almost indefinite shelf life that is inexpensive and takes almost no room to store?
That something is the chemical Calcium Hypochlorite more commonly known as Pool Shock. Now, don't be "shocked" by the thought of water purification via swimming pool chemicals. We'll show you how to do it safely. A 1-pound bag of calcium hypochlorite in granular form will treat up to 10,000 gallons of drinking water Calcium hypochlorite is one of the best chemical disinfectants for water, better than household bleach by far. It destroys a variety of disease causing organisms including bacteria, yeast, fungus, spores, and viruses.
