For laundry bleaches: 1 gallon is required for every 1000 gallons of water, and there are 1500 gallons of water in the well. Therefore, 1 ½ gallons of laundry bleach is required to disinfect this well.
A general rule of thumb to shock chlorinate and disinfect a storage tank is to mix non-scented NSF-approved household bleach (5.25% chlorine) in the reservoir at the ratio of 1 gallon of bleach for every 1,000 gallons of water (i.e., 1 quart for every 250 gallons of water).
Add 1 tablespoon of 5%-6% unscented liquid household bleach for every 100 gallons of water in your cistern to prevent microbial growth.
In a clean, freshly filled 500 gallon wading pool, add a quarter cup of unscented household liquid chlorine bleach to the water. Then, at the end of each day, test the water and add an additional 1/8 to 1/4 cup, depending on the reading.
Sanitizing Procedure
In a clean quart container about half full of water, put 1 to 1 1/2 fluid ounces (2-3 tablespoons) of a standard unscented, non-detergent household chlorine bleach (5.25% concentration) for every 500 gallons of water to be treated. Pour the bleach solution directly into the storage tank.
If the water is clean and clear, then add about 3 oz of liquid chlorine per 1000 gallons of water – while the pool filter is running. This should give you a chlorine level of about 3 ppm.
Household bleach, Clorox and liquid chlorine can all be used to sanitize a pool. They are all types of chlorine. Household bleaches such as Clorox usually contain about 5-6% available chlorine, about half that of pool liquid chlorine. Household bleaches often have unwanted fragrances and colors.
You'll need 1/4 cup of bleach for every 16 gallons of water in your freshwater tank. This also equates to one ounce per eight gallons.
Most RVers recommend 1 full cup of bleach for every 50 gallons of water tank capacity. Thus, if your water tank can hold 100-gallons of water, use 2 cups of bleach. If your tank holds 25 gallons, use 1/2 cup.
"The biggest don't when it comes to toilet tanks is bleach — do not use bleach or products containing bleach inside the tank, as it can corrode the internal parts of your toilet," says Patty Stoffelen, a bath fixtures merchant for The Home Depot to Martha Stewart.
How much shock do I need to shock my pool? A simple ratio and a standard rule of thumb to follow when you shock your pool is to dissolve one pound of either calcium hypochlorite or sodium dichlor for every 10,000 gallons of pool water.
Clorox itself recommends using between 100 and 200 ounces of regular-strength bleach per 10,000 gallons of pool water -- one gallon is 128 ounces, and many bottles of bleach are available in one-gallon or half-gallon sizes.
To disinfect a surface, the CDC recommends about 5 tablespoons of regular bleach per gallon of water. For a liquid pool shock, it is preferred to dilute it at a rate of 2.5 to 3 tablespoons per gallon of water. For a 5,000-gallon pool, you need 3 cups or 24 oz of Clorox bleach to raise the chlorine level.
*1 gallon of chlorinating liquid delivers the same amount of chlorine as 2 chlorinating tablets.
Now you can know the gallons of bleach you would need to shock your pool as follows: use 0.5 gallons of Clorox per 10K gallons of water to increase the level of chlorine by 5 ppm. If you want to raise the level of chlorine by 2.5 ppm, then you would need ¼ gallon of the product per 10K gallons of water.
There's a protocol when using Clorox® Regular Bleach2 for swimming pool disinfection. On an ongoing basis, if you super-chlorinate the pool with 100-200 oz. bleach per 10,000 gallons of water, in addition to regular chlorination, algae growth can be prevented.
75 ounces per 3,000 gallons every week. Initially you will need stabilizer to protect the chlorine from the sun. This is added at a rate of one pound per 3,000 gallons of water. Pre-dissolve in warm water, then add to the pool.
Chlorine levels up to 4 milligrams per liter (mg/L or 4 parts per million (ppm)) are considered safe in drinking water .
For the greatest protection against algae, bacteria, and cloudy water, Intex pools should maintain a chlorine level of 2.0-4.0 ppm at all times.
You need to use four and a half cups of bleach for a 55-gallon barrel.
Add 1/4 teaspoon (16 drops) of bleach per gallon of water if the water is cloudy and 1/8 teaspoon (8 drops) if the water is clear.
4) Work out how much bleach will be needed: For every 50 gallons of water in the well use one quart of laundry bleach - (4 quarts in a gallon).
