You should use one tablet per week for a kiddie pool of 200 gallons or less, and two tablets weekly for kiddie pools of over 200 gallons.
Many of us want to cool off in a backyard pool, but we also want to make sure there are no dangerous bacteria lurking in these pools that do not have any filtration system in place. You can use Clorox® Regular Bleach2 to treat the water in a child's wading pool.
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 In Small Inflatable Pools
For small inflatable pools that you don't want to empty and refill so often, you can add a small amount of bleach to the water to sanitize it. Add about a 1/4 tsp for every 10 gallons of water, or for medium sized inflatable pools, add 2 1/2 tsp for every 100 gallons.
If your kid's pool is pretty small, and draining and refilling it doesn't feel like a colossal waste of water, then the best way to keep the kiddie pool clean is to drain it when the water's dirty, scrub it down with a plain old kitchen brush and some mild dish soap, and refill it.
For most inflatable pools or plastic kiddie pools following the guidelines listed above, the water should be changed every two weeks at a minimum. If you are not adding chlorine to kill bacteria, drain the pool every other day.
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.
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.
How do I keep a kiddie pool clean without chemicals? If you simply do not want to use chemicals to keep your kiddie pool clean, there is an alternative. Rather than chlorine, use Distilled White Vinegar. Add 1/2 Cup for every 100 gallons of water in your pool.
“It's important to change the paddling pool water every day – drain it and let it dry at the end of the day and use an anti-bacterial spray to kill any germs so it is safe to use the next day.”
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. Pool professionals tend to recommend more conservative amounts of bleach.
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.
To keep the pool clean without a filter, it is necessary to use chlorine with a flocculant or to use a flocculant chemical. This product groups the impurities that float in the water, causing them to fall to the bottom of the pool so that they can be removed later with a cleaner.
Of course, too much chlorine in pool water can be dangerous. Exposure to over-chlorination can provoke asthma, lung irritation, and potentially skin and eye irritation. As well as being potentially bad for you, it's bad for your pool.
Best time is either after sunset, or when you need it. Bleach doesn't lose concentration overnight unless it has something to work on. In fact, a good way to tell if your pool is in good shape is to do an overnight chlorine test. Ideally, the FC at night should be the same as the FC level the next morning.
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.

With excessive debris in the water like leaves, pine needles, and dirt, the pool walls will get slimy and grow mildew faster.
If the chemicals used to kill germs (chlorine or bromine) in pools, hot tubs, and water playgrounds are not kept at the right level, these germs can multiply and make swimmers sick.
Clean and disinfect the kiddie pool after each use: Drain or empty the pool after each use. Leaving the pool full overnight is unsafe, both because it is a potential drowning risk and a potential waterborne disease risk.
Clean Your Pool with White Vinegar and Water
A simple and non-toxic way to clean a paddling pool is to clean it with white vinegar. White vinegar is great for cleaning because it can remove all the horrid bacteria that sets up up home in your paddling pool. It's also colourless, so it won't stain the pool either.
