Making Bleach from Pool Shock

Aka Calcium Hypochlorite

Aka Calcium Hypochlorite

Skyowls wife discussed this but the site she referred to is for sale and cannot be accessed! So I thought I would put the actual formula on our site.

I have been able to find the math that determines the ratio of water to calcium hypochlorite of whatever percent you have to work with. Here is the basic formula.

__Weight of water X parts per million you want in your solution__

1,000,000 X percent of calcium hypochlorite you have in decimal form

Okay, water weighs 8.3454 pounds per gallon or 133.5264 ounces per gallon or 3785.4118 grams per gallon

each cup of water weighs .5216 pounds or 8.3454 ounces or 236.5882 grams

Parts per million are found like this:

Whatever percent solution you want you multiply by 10,000 (1% of a million) so

For a 6% solution of BLEACH you multiply 10,000 X 6 = 60,000;

For an 8.5% solution of BLEACH you multiply 8.5 X 10,000 = 85,000;

For a 10% solution of BLEACH you multiply 10,000 X 10 = 100,000 and so on.

Now for the bottom half of the formula:

if you have 68% calcium hypochlorite pool shock so you multiply 1,000,000 X .68 = 680,000

If you have 73% calcium hypochlorite pool shock you multiply 1,000,000 X .73 = 730,000 and so on.

So here is the formula with the numbers plugged in using 3 quarts and 1 cup of water (13 cups) and 68% calcium hypochlorite. I’m using ounces instead of grams because the numbers are smaller and instead of pounds because that is a tad more accurate.

__108.4902 oz X 100,000__=

1,000,000 X .68

__10,849,020__= 15.9544 oz

680,000

Close enough to use a one pound bag.

I hope this make sense to everyone.
