The bleach recommended for pools is chlorine. If you don't want to keep emptying and refilling your small inflatable pool often, this is an option. But, use the right amount of chlorine bleach for pool sanitization. The standard measurement is a quarter teaspoon for 10 gallons.
Small inflatable or plastic kiddie pools and water slides don't have the same protection against germs that a swimming pool, hot tub, or water playground do. That's because it is unsafe to add germ-killing disinfectants, such as chlorine or bromine, to the water in kiddie pools and water slides.
Baking soda will raise the total alkalinity of the water. The alkalinity keeps the pH stable which then allows the bleach to remove more bacteria and contaminates. About a 1/2 of a teaspoon of baking soda will treat 26 gallons of water.
Many of us use household bleach, a common brand name being Jik, to clean our homes. Bleach itself is a diluted solution of sodium hypochlorite and it is this ingredient that can be used to lighten, sanitize and disinfect.
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.
Use a solution of warm water and white vinegar for a pool that is only slightly grimy. You only need about 1 part vinegar to 10 parts water. Dip your rag in the solution and wipe the pool clean. Toss the rag in the trash.
Use Chlorine Tablets
The best way to obtain a constant, consistent chlorine level in the pool is to use 1″ tablets or 3″ tablets in a floating chlorinator, aka chlorine floater. Most inflatable pools need just half of one 3″ tablet per week, or several 1″ tabs at a time, replaced promptly when they dissolve.
If a kiddie pool's water isn't going to be changed regularly, disinfecting it makes sense, and bleach will work well in that regard. Add only enough bleach to a kiddie pool to maintain chlorine between 1 and 2 parts per million (PPM), and test to ensure proper levels.
Although inflatable pools don't need to use chlorine, it's one of the most common ways to keep pool water sanitary and safe to swim in. The chlorine is used to efficiently kill bacteria in the water that may be harmful to swimmers. Larger inflatable pools will benefit the most from the use of chlorine.
I think the answer to your question is about 3-6 days. The problem is that the chlorine that you need to keep the bacteria in check is used up more quickly as the temperature rises, the activity increases, and as sweat and other body stuff is put into the pool.
What can you use instead? 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.
It is a good idea to wait at least 20 minutes after adding the water balancing chemicals. If you use calcium chloride in your pool, you should wait at least 2 hours to swim.
There are alternatives to chlorine including bromine, ionizers, and ozonators, though with each you'll still need to use some chlorine. A fourth alternative is PHMB, which doesn't require the use of any chlorine. All four have drawbacks, including cost. Chlorine is relatively cheap.
Domestos is a British brand of household cleaning range which contains bleach (primarily sodium hypochlorite NaOCl).
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.
The strongest bleach is Clorox Regular Bleach2, which is the best bleach for cleaning, stain removal, and whitening. It's the only bleach that can be used around the house to clean and purify a wide variety of surfaces.
Don't bother running electric for an intex pool. They're meant to be temporary structures. Without a pump/filter using your vacuum to move around the water is your best bet.
Intex pools -- the same as with all other swimming pools -- require a filter, pump and the appropriate chemicals, such as chlorine, to keep the pool water clean and sanitary for swimmers.
It is very important to drain the kiddie pool completely after every use. Allow it to fully dry under the heat to get rid of any moisture left. For cleaning, you can use bleach or vinegar (diluted in water) to disinfect it.
