Bleach, like any other kind of pool treatment, is best used in specific concentrations -- that is, you'll want to be able to detect a certain amount of chlorine in your pool water. Too little, and you won't effectively sanitize your pool water and surfaces. Too much, and your pool water might become too harsh to use.
6 reasons why you should avoid disinfecting your pool with bleach instead of chlorine. Finally, if it is not properly dosed, bleach can become dangerous for bathers! Pool water that is too concentrated in bleach can become toxic, irritating the eyes, skin and respiratory tract of swimmers.
If you need to calculate how much bleach or Clorox you need to shock your pool, you will have to use 1/2 gallon of bleach per 10,000 gallons of water to raise the chlorine levels by 5 ppm.
Using Bleach as a Shock
You need to use less of such products per volume than you do if you simply add chlorine, and if you opt for chlorine alone, you need more bleach than you do pool chlorine. Bleach contains the same chemical -- sodium hypochlorite -- as pool chlorine, but the concentrations are different.
High concentrations of chlorine (above 1.5 ppm) will attack the liner and bleach it, thus damaging it. Any level below this range will weaken its ability to kill off bacteria. The addition of chlorine to your pool water has to be done in a careful manner.
Depending on how much you have added and the size of your pool, it is generally safe to wait about 4 hours after adding liquid chlorine or until levels reach 5 ppm or lower.
They are identical in every way, with the exception of strength. Household bleach is usually a 6% concentration (although some of the cheaper stuff is 3%), while pool chlorine can typically be found in strength between 10% and 12%. All of this is sodium hypochlorite, and works the same in sanitizing your water.
Mix required amount of Clorox® Regular Bleach2 with 2 gallons of water and scatter over surface of pool. Mix uniformly with pool water. Empty small pools daily. (Clorox® Regular Bleach2 will not harm plastic pools.)
After your cyanuric acid level is set, add the bleach. Then proceed with daily testing until you understand how much chlorine your pool uses. At this point, chlorine maintenance can be as simple as adding a little bleach to your pool every day to keep it within the target levels.
Chlorine is much stronger than bleach. To get your pools chlorine level to the point it needs to be to keep the pool looking clean and bright; you will need to use more bleach than you will chlorine. Bleach is also going to come in a liquid form only, and chlorine is most commonly sold in tablets.
But excessive exposure to chlorine can cause sickness and injuries, including rashes, coughing, nose or throat pain, eye irritation and bouts of asthma, health experts warn. Instructions for safely chlorinating a pool usually call for a maximum of four parts per million when people are in the pool.
Other chemicals
Bromine — considered a safe substitute for chlorine. Looks for BCDMH tablets, which are typically 66% bromine and 27% chlorine. If unable to find, you can use just bromine but it may leave the water a dull green color. PHMB — Chemical compound named polyhexamthylene biguanide.
It is possible use use the tablets in your large wading pool. However, this is not economical and it will take a large amount of tablets to clean your pool. Unless you have a major supply of these tablets on hand, I would not suggest using them to clean a pool.
Most floating chlorinators can hold anywhere from two to eight weeks worth of chlorine, depending on conditions such as the season and your pool's size. An automatic feeder works in a similar way, allowing it to mix with the pool water slowly and deliberately.
If your chlorine test turns orange, your pool water has a very high chlorine content, above 4 ppm. Stop using chlorine until the chlorine test shows a result within the normal range. If you want faster results, use a chlorine neutralizer to bring chlorine back into the proper range.
The standard ratio for pool chlorine and water is 10:90. It means you need to mix 90% water with 10% of pool chlorine. It's a standard ratio.
Myth #1: Bleach contains free-standing chlorine.
There is no free-standing, or elemental, chlorine in bleach. Bleach is manufactured from salt and water to produce sodium hypochlorite, the active ingredient in bleach. Bleach is simply a water solution of this compound.
Bleach Versus Pool Chlorine
In addition to the chlorine itself, calcium and other inert ingredients make up the remainder of the chemical. Household bleach is a liquid that contains sodium hypochlorite, which is simply chlorine in its liquid form. Bleach, however, is typically only 5 to 6 percent chlorine.
Though other brands are available at under $1, people still buy Clorox that costs them $3 per bottle. What is the difference between Clorox and Bleach? Bleach made by Clorox is so popular that bleaches made by other companies are considered inferior, though, there is basically very little difference between the two.
Not all bleach has chlorine in it. In fact, more and more cleaning products are using hydrogen peroxide instead. The label will always indicate if it's a chlorine bleach or a non-chlorine bleach. When in doubt, read the ingredients list: If it is made with sodium hypochlorite, it's a chlorine bleach.
To use this solution to purify drinking water, add 1 part chlorine solution to 100 parts water, according to the EPA standards. So take the ounce capacity of your chose vessel (say 64 ounces) and divide it by 100. This would be . 64 ounces or approximately 2/3rds ounce.
One pound of 65% Cal-Hypo is equivalent to 117 fluid ounces (0.91 gallons) of 8.25% bleach. One pound of non-chlorine shock (43% MPS) is "equivalent" to 36 fluid ounces (0.28 gallons) of 8.25% bleach, but non-chlorine shock is not the same as chlorine.
Shock. Common unscented household bleach (sodium hypochlorite) works well to shock a pool. To increase the chlorine level by 5ppm in a 10,000 gallon pool, you would need 1/2 Gallon of basic household bleach.
