I know about the liquid bleach and how much to use but how much of the power pool shock does one use?
You can use a non-scented, household chlorine bleach that contains a chlorine compound to disinfect water.
Do not use non-chlorine bleach to disinfect water. Typically, household chlorine bleaches will be 5.25% available chlorine. Follow the procedure written on the label. When the necessary procedure is not given, find the percentage of available chlorine on the label and use the information in the following table as a guide. (Remember, 1/8 teaspoon and 8 drops are about the same quantity.)
Available Chlorine Drops per Quart/Gallon of Clear Water Drops per Liter of Clear Water
1% 10 per Quart - 40 per Gallon 10 per Liter
4-6% 2 per Quart - 8 per Gallon (1/8 teaspoon) 2 per Liter
7-10% 1 per Quart - 4 per Gallon 1 per Liter
(If the strength of the bleach is unknown, add ten drops per quart or liter of filtered and settled water. Double the amount of chlorine for cloudy, murky or colored water or water that is extremely cold.)
Mix the treated water thoroughly and allow it to stand, preferably covered, for 30 minutes. The water should have a slight chlorine odor. If not, repeat the dosage and allow the water to stand for an additional 15 minutes. If the treated water has too strong a chlorine taste, allow the water to stand exposed to the air for a few hours or pour it from one clean container to another several times.
You can use granular calcium hypochlorite to disinfect water.
Add and dissolve one heaping teaspoon of high-test granular calcium hypochlorite (approximately ¼ ounce) for each two gallons of water, or 5 milliliters (approximately 7 grams) per 7.5 liters of water. The mixture will produce a stock chlorine solution of approximately 500 milligrams per liter, since the calcium hypochlorite has available chlorine equal to 70 percent of its weight. To disinfect water, add the chlorine solution in the ratio of one part of chlorine solution to each 100 parts of water to be treated. This is roughly equal to adding 1 pint (16 ounces) of stock chlorine to each 12.5 gallons of water or (approximately ½ liter to 50 liters of water) to be disinfected. To remove any objectionable chlorine odor, aerate the disinfected water by pouring it back and forth from one clean container to another.

From the Army manual, to make a concentrated chlorine solution that you can use for disinfecting water (or to be used in maintaining a clean and sanitary living environment), you'll want to use calcium hypochlorite that has around 70% available chlorine.From there, the article says you use the homemade liquid bleach the same way you'd use purchased liquid bleach, 8 drops (or so) to a gallon of water.If you're buying pool shock, on the back of the bag it will tell you what percentage of chlorine is available. The one I use is called "Zappit 73 Pool Shock, it is pure calcium hyphochlorite that contains up to 73% available chlorine and sells for around $ 5 for a 1lb bag.
To make the homemade chlorine bleach solution, you'll need to do the following:
- Mix 2 level Tablespoons of Calcium Hypochlorite to 3 cups of water.
