While a typical free available chlorine level is recommended at 1-3 parts per million (ppm), without the pump or filter, you should maintain somewhere in the 3-4 ppm range to prevent debris, algae and other problems from potentially developing.
Shock-chlorination is an essential and effective method of cleaning the pool. But you need to have the pump circulating the water for this to be effective.
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.
It's always best to run the pool pump during the hottest times of the day. The sun is one of the causes of chlorine depletion in your pool. The water moving around helps protect the chlorine from being burnt out from the sun.
You very well may end up with a green pool. When you cannot circulate water, the water stagnates and chemicals tend to settle out in the lower levels of the pool. It makes it almost impossible to add any chemicals because you don't have a good way to mix the water.
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.
Without Chemicals
If a parent chooses not to use chemicals in the kiddie pool, the water must be drained after the children are done using it. This should occur within 24 hours. That means the parents must go through the hassle of filling the pool with fresh water each day.
In the industry it is recognized to have the pool run for 3 hours at a bare minimum up to 24 hours. 24 hours really is overkill but it'll ensure the water is completely mixed with the chemicals.
If your pool pump manufacturer has declared your pump is rain safe, you can leave it on in rainfall. Nevertheless, during a thunderstorm, it is highly recommended that you switch off and unplug your pool pump to prevent any costly and irreversible damages to your pool equipment.
Every pool must turn over at least once a day, so most pool pumps should run approximately 8 hours a day.
You can do your own pool work, including using chlorine--even without a filter.
The procedure for adding granular chlorine is pretty much the same as adding calcium chloride or sodium bicarb to a pool. Measure the dry chemical, pre-dissolve in a bucket, and pour around the perimeter of the pool (never into the skimmer directly). There are a few types of dry, granular chlorine.
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.
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.
Pour the liquid chlorine into the pool with the jug as close to the water surface as possible in order to prevent splashing. Add the liquid chlorine to the deep end of the pool. After all of the liquid chlorine has been added, brush the walls and floor of the pool.
You should cover your pool every night for several reasons. First off, a pool cover saves energy and conserves water by decreasing the amount of make-up water. Also, it reduces the consumption of chemicals, and finally, it saves a lot of cleaning time since it keeps the debris out of the pool.
Shocking your pool isn't necessary, although, it's not a bad idea either. If you get an extremely heavy rain fall, you could shock your pool for good measure. This will help fight off any contaminants that the rain may have brought to your pool.
Give your pool a good shock treatment 1 to 2 days before the storm hits. You can bring the chlorine level up pretty high to prolong the pool being depleted of chlorine.
Adding Shock Directly Into The Pool Water
Don't worry—you can't overshock your pool. But beyond fashion faux pas, adding shock directly to the pool water if you have a vinyl liner can be a disaster. The shock granules will sink the bottom and bleach out your liner.
Chemicals that you add to your pool while the water is circulating don't need to be recirculated; they will stay mixed even if you don't pump the water continually. Although it's generally recommended that all the pool water undergo filtration every 24 hours, the pump does not need to run all the time.
Running the pump at night should only be when you are doing a major chemical treatment such as algae clean-up. Your pool is more vulnerable during the day, plants don't grow at night the way they do during the day–that's true of ALL plants including Algae.
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.
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.
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.
