Swimming pools need chlorine to keep the water clean and safe to swim in. Chlorine helps keep water clean by preventing the growth of algae. It keeps your pool water safe by attacking and neutralizing harmful bacteria and microorganisms. The magic of chlorine is in a simple chemical reaction.
Statistically, a pool without chlorine is more likely to make you sick because of the possibility of being exposed to the things not contained or killed by chlorine. Remember, your skin is porous, so microscopic impurities can pass through. A pool sans chlorine is akin to a big puddle of murky water.
If the chlorine smell is very strong, however, you may soon spot “red-eyed” swimmers emerging from the pool. That's when the pool water is assumed to have “too much chlorine” in it. Ironically, a strong chemical smell around the pool and “swimmer red eye” may be signs that there is not enough chlorine in the water.
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.
Pros of Saltwater Pools
They're gentler on the skin, with less irritation to the eyes, hair and swimsuits. The water has a softer, silkier feel to it compared to chlorine water. They have lower maintenance costs than chlorine pools. There's no need to store harmful chemicals.
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.
When water sits in place for too long and is exposed to an unsterile environment, it becomes contaminated. Swimming in stagnant water can expose you to serious health hazards. Stagnant water becomes a breeding ground for parasites, mold, and bacteria.
Daily as needed and indicated by measurement. One caveat, however: if your total alkalinity and pH are not where they should be, you will find it difficult to keep enough free chlorine in your pool water. Adjust your alkalinity first, then correct your chlorine.
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.
If the water is clean and clear, then add about 3 oz of liquid chlorine per 1000 gallons of water – while the pool filter is running. This should give you a chlorine level of about 3 ppm.
Chlorine is essential for pool water because it kills harmful algae, bacteria and microorganisms. Unfortunately, chlorine breaks down when exposed to the sun and chemicals from sunscreen, sweat and more. A pool should have a chlorine level between two and four parts per million (ppm).
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.
A chlorine level of between 3-5mg/l must be maintained in your hot tub at all times. The addition of chlorine will depend upon usage and bathing habits. It could be daily or every 2-3 days (for 1mg/l add 2g per 1000 litres).
How Often Should I Shock My Pool? Shocking your pool regularly will help to keep the water clean and free of contaminants. You should aim to shock your pool about once a week, with the additional shock after heavy use. Some tell-tale signs that your pool needs to be shocked are cloudy, foamy, green, or odourous water.
Answer: Yes, when using tablets they can be present in the water while you swim. Also confirm with a test of the chlorine level to be sure the sanitizer level is safe for swimming.
If ground water is not a problem a pool can be left empty for weeks or even months as long the hydrostatic relief in the bottom of the pool is open and functioning. If the time frame of the pool being empty gets into freezing weather there is real risk of freeze-thaw damage to surface of 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. So, it's best to have your pump ready as soon as possible.
Now you can know the gallons of bleach you would need to shock your pool as follows: use 0.5 gallons of Clorox per 10K gallons of water to increase the level of chlorine by 5 ppm. If you want to raise the level of chlorine by 2.5 ppm, then you would need ¼ gallon of the product per 10K gallons of water.
The basic difference between chlorine and bleach is that chlorine is a natural element, while bleach is a solution of many elements. Moreover, chlorine occurs in nature as an essential part of plants and animals. It also can take shape in two states of matter – gas and liquid.
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.
