after shocking pool when can you swim

Hygiene is the crux of everything, especially when it comes to body contact. Who wants to enter a germ-filled, dirty swimming pool, nobody I guess!!! 

The American experts (The US Centre for Disease Control and Prevention) have mentioned that chlorine should be added to a pool to keep it germ-free. Even the swimmers have to make sure that the pool is totally safe and hygienic for them to swim. 

If the water of the pool is not sanitized properly then there are chances that anyone can get exposed to infections like water in swimmer’s ear, diarrhea, skin infections or even athlete’s foot. All these things appear so scary, so why not keep the pool purified properly?

How To Keep The Pool Sanitized?

Chlorinating the pool is one of the best methods. Shocking the pool keeps the pool free of germs and also keeps harmful microbes away. Three to four times the normal amount of chlorine should be added to the pool. Whenever chlorine is added to the pool it becomes necessary not to use the pool for some time.

The pool shock should not be done on a daily basis. Whenever chemicals are added the chlorine level of the pool suddenly rises. If we have good pool vacuum and a saltwater generator then the need for chlorinating the pool arises very less than normal.

How Long Should I Wait After Chlorinating?

The biggest concern for any pool owner is that for how much time one should wait to step inside the water. Though there are no strict rules or consensus on this, generally, we can follow some sort of rules for swimming in the pool.

How Much Is The Pool Unclean?

First and foremost, a thing which should be assessed is that how much is the pool dirty. If we talk in general then within an hour or so the chemicals become a part of water after they are added.

The balancing chemicals like pH, calcium hardness, and alkalinity mix in the pool roughly in an hour. A few convincing factors have to be discussed before making the swimmer know when to swim. A time frame has to be made for this. Even according to Health Canada, the microorganisms which cause diseases should be removed or kept away for maintaining pool hygiene.

Some of the pools are swampy at the bottom. In this case, the chlorine has to be added to the pool in larger amounts as compared to normal (5 to 10 times) than a normal dosage. When after rainy days the chlorinating has to be done a little lesser. Extensive treatment is required if the pool is having a lot of algae formation. It might take days or weeks in some cases. Serious conditions have to be treated seriously.

Large doses lead to the breakdown of bacteria, organic waste, etc.  So, one thing we can mention here that every pool has a different constraint attached to it, so the time for using the pool varies accordingly.

In short dirtier the pool, more is the time required for using it. The pool owners need to invest a lot of effort to keep the pool at its best.

What Type Of Shock Being Used?

Since we are living in modern times, many types of products are available in the market, the same goes for shocks. There are shocks available with chlorine and without chlorine.

The most popular or commonly used shock is with chlorine or Cal-hypo. The basic difference we can see is in the concentration or the presence of active ingredients in the different types of shocks available.

The shocks which are chlorine-based have a higher level of pH as compared to the ones which have a lower pH (the non-chlorinated ones).

The chlorine-free shock comes with a neutral pH and shock oxidizes bacteria and chemicals in the pool without chemicals. Since the chlorinated shock takes a longer time to interact with the pool so it is advisable to wait for a little longer time to enter into the pool. The chlorine-free shock allows the swimmers to enter in the pool within an hour.

The pH level and chlorine levels of the pool get disturbed, so it is recommended to take a timely check before returning inside the pool.

Exactly……. How Long To Wait to Swim After Shocking Pool?

As discussed earlier, the different types of chemicals are there so let’s see how they work

On Adding Floc  

In this case, it is safe to wait, as it takes time for the floc to settle properly at the bottom and after the pool is vacuumed to waste then only it is ready for use.

After Adding Muriatic Acid

At least one should wait for 30 minutes after adding it to the pool, as the acid might create a hot spot leading to skin rashes.

On Adding PH, Alkalinity, And Clarifier

In this case, 20 minutes to an hour is the recommended time.

After Adding Calcium Chloride To Raise Calcium Hardness

One should wait for at least 3-4 hours

On Adding Liquid Chlorine

It depends on the pool size and the amount added. Until the level reaches 5pmm or lower, it has to be ensured.

After Adding Algaecide

Most of the algaecides are safe to swim with. A short duration of 15 mins is advised to wait for.

Shocking The Pool

Test first!!!! The time duration of 24 hours to be waited for, till the levels normalize.

Most of the companies provide the instructions on the back, just go through them and follow religiously. 

Enjoy your cool pool…!!!
