Letter Re: Clarification on Calcium Hypochlorite for Water Purification

…things more confusing, they offered another brand of this that had 47% Calcium Hypochlorite. Please help close the gap on this topic as it is such an important one. – The Wanderer JWR Replies: The problem with most retail store employees these is that they are marginally qualified to run a cash register, but little else. To most of them pool water chemistry is an arcane art–not rational science. Don’t ask them chemistry questions! A granular (dry powder) “pool shock” product that lists only Calcium Hypochlorite as the active ingredient should be safe to use for water purification. The problem with other varieties is that they include other algaecide or fungicide chemicals that are probably not safe for human consumption. Ditto for using liquid bleach for the same purpose.ou want to buy Calcium Hypochlorite bleach. Do NOT buy bleach with fabric softeners, scents, et cetera. Keep in mind that bleach




Learning Food Storage From Hard Experience, by PitbullRN

…corn, and carrots, which may have had rust on the outside, but still held the contents, every single can of tomatoes had leaked their contents and the cans rusted from both moisture and tomato acid. The Clean-Up The good news is that I was able to salvage a lot. Over the next months, I was able to remove each item and hand wash it in a strong chlorine bleach solution. (Of course, I wore an N95 mask and heavy duty Platex gloves whenever in the storage room or using the chlorine bleach.) I would note the contents of the #10 can, along with the number of servings prior to cleaning, as the paper label would usually disintegrate with the cleaning. I would then use a permanent marker to label the can before placing it on new shelving in the general area of our (floored) basement. If there was any rust…

For a long duration pandemic (and any serious one will be long duration with multiple waves), consider learning how to create bleach from calcium hypochlorite. Some brands of pool shock are calcium hypochlorite with some inert ingredients, so it’s easy to acquire…just make sure you know ratios and most importantly how to safely use and store the calcium hypochlorite. I keep the directions stored with both plastic measuring scoops and the safety gear next to my plastic tub with the sealed pool shock packages. RM Good…




Pseudo-Currency: Items You Can Trade Like Cash Or Use Yourself if the Balloon Goes Up, by Scott in Wisconsin

…powder / pool shock)  1 lb bags cost just $3.50 at inyopools.com and will make roughly 12,000 gallons safe for drinking.   I’ve put away 4 bags.   1/8 oz of the powder will make a gallon of Chlorine Bleach.  So each 1 pound bag makes about 1,000 pints of Bleach.  Each pint of Bleach will then disinfect 12+ gallons of water. Pint-size plastic bottles should be very common, and part of your own water storage stash.  As a business, you could sell or trade pints of Chlorine Bleach that you have made with your powder.   A quick whiff of the bleach should convince your customers that it’s genuine.  Your customers can then disinfect 12 gallons of water that they acquire on their own.  You can have a business, and maybe save lives at the same time. Seeds.  Once things shake out, many people will be anxious to get a garden started. …
