I'd like a little help from someone that stores calcium hypochlorite for water purification , and is aware of the dangers it poses while handling it....it seems a little ridiculous that the governmental agencies can't come up with a more user friendly formula than

for high strength calcium hypochlorite... mix a stock solution of 1 heaping teaspoon in two gallons of water, then treat at a ratio of 1 part stock solutiion to 100 parts water (1:100), let stand 30min

if a heaping teaspoon is for two gallons
1/2 heaping teaspoon is for one gallon
1/4 heaping teaspoon is for 1/2 gallon
then 1/8 heaping teaspoon for one quart

I don't have a 1/8 teaspoon measure on hand, but just for grins measured out a heaping teaspoon of sugar as a calcium hypochlorite substitute, and found that by using a piece of 9mm brass, it took 8 "brass fulls" , or the casing held a volume of 1/8 "heaping" teaspoon


can someone that measures their pool chlorine with a test kit see how close you get to 3ppm (parts per million) with

one 9mm case full of calcium hypochlorite dissolved in a quart of water to make a stock solution

and since you need a final dilutiion of 1 part of stock solution to 100 parts of water to be treated...add 38mL of the stock solution to a gallon of water, let stand, and test

1 gallon water is 3.8 liters (L) or 3800 mL
38mL of the stock solution then is 1/100 of a gallon

edit... 9 teaspoons (measuring spoon not coffee spoon) is real close to 38mL

this might be of value to others, and would like to see what the chlorine concentration in parts per million is..., thank you for your consideration
