Short answer--yes. The first response, however, would be why would you use a pool without a filter? The sand filter or other filtration system is essential to the health and safety of the swimmers. It is also necessary to have a circulation pump for maximum chlorination.
Pool pumps typically disperse chlorine into the water for you, but it is possible to add chlorine without a pump. The easiest way to do this is with chlorine tablets. They go in a designated floating container and slowly dissolve while floating around the pool. You can also use inline chlorinators.
It all depends on the type of pool and the chemical levels in the pool. Your pool can keep running for a few days with no problems while without a pump. However, know that a standard pool needs a pool running for at least once in 24 hours, or you might notice an algae bloom.
Chemicals are only half of the equation when it comes to your pool water clarity. So yes, while it's perfectly fine to run your pool pump without a filter cartridge installed, it's better to have a backup filter cartridge to ensure that you don't have to run it without one.
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.
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.
Your Pool Will Turn Green
High sunlight, muggy temperatures, low levels of chlorine, or the buildup of phosphates, carbon dioxide, or nitrates can result in a green pool.
A pool can only be safe for swimming without a pump for a few days and a maximum of one week. The definite number of days the pool will be safe will also depend on the temperatures of the water, the weather at that particular time, the level of chlorine, and how clean the pool was before the pump stopped functioning.
Remember, NEVER disperse chlorine granules or tablets directly into the water. This is dangerous to swimmers' health and will absolutely result in concentrations of chlorine that will damage your pool.
It takes a lot of chemicals to make pool water safe for swimming. Untreated water can accumulate harmful Escherichia coli and Salmonella bacteria and protozoans such as Cryptosporidium parvum and Giardia lamblia.
Maintenance is critical when it comes to the quality of your pool water. Well maintained pool water can last up to 5, maybe even seven years before you need to replace it. This means weekly cleaning, functional filters, and checking ph levels every day. Usage is a huge determining factor.
Swimming pools need chlorine because chlorine is the only effective way to keep pool water clean. Even a saltwater pools need chlorine (they just generates the chlorine themselves). While there are other methods of cleaning pool water, such as UV or ozone treatment, they are not replacements for chlorine.
Pool water cannot be used to water plants unless the chlorine content is reduced. Chlorine eliminates bacteria and algae in pool water by disinfecting or killing action. It also oxidizes other materials such as dirt and chloramines and can harm plants in high quantities.
Shock is liquid or granular chlorine. You should add one gallon (or one pound) of shock per 10,000 gallons of pool water every week to two weeks. During hot weather or frequent use, you may need to shock more frequently.
Chlorine serves a vital purpose in keeping swimming pool water clean and healthy. In theory, if you have a cloudy swimming pool, you can add chlorine to “shock it” and clear things up. Chlorine will get the job done.
Chlorine is added to the water to kill germs. When it is added to a swimming pool, it forms a weak acid called hypochlorous acid that kills bacteria like salmonella and E. coli, as well as germs that cause viruses such as diarrhea and swimmer's ear.
Drinking water chlorination is the addition of chlorine to drinking water systems. It is the most common type of drinking water disinfection. Disinfection kills bacteria, viruses, and other microorganisms that cause disease and immediate illness.
In fact, chlorine can be harmful to your eyes, hair, nails, lungs, and yes, even your skin. Not only that, but depending on your age, existing skin condition, and several other factors including the balance of chemicals in the water, chlorine can be anything from irritating to extremely harmful to your skin.
You can purchase pool filter cleaner, but some pool owners choose to make their own. One method is to fill a bucket with warm water so that it's deep enough for the cartridge to be completely submerged. Then, add one cup of liquid dish soap or dishwasher detergent for every five gallons of 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. If you opted for the Intex Salt Chlorinator, you can make your own chlorine by adding the correct amount of Pool Salt to the water.
Chlorine tablets are slow dissolving and therefore need to be placed in either a floating dispenser, in-line chlorine feeder or a skimmer basket.
