How to Lower Chlorine in a Pool?

I have seen many times how much chlorine in excess can make a pool unhealthy. Yet, I have found most pool owners indifferent to the importance of keeping chlorine levels low. You can understand by writing a recent fact about this.

One of my well-known clients was Mollie W. Briscoe, who lived in Fort Arbutus Drive, Florida. She has a luxury Above ground pool, which was installed by my team. A few days ago- She called me to check the pool water. She didn’t just knock me out; I just went and realized. Red rashes appeared on various parts of her face, hands, and feet within minutes of leaving the pool at noon. Earlier, as a result of swimming with her baby girl in the pool, asthma appeared. All in all, they suspect that the pool water has been wasted, so the germs have started attacking.

How to Lower Chlorine in a Pool

Of course, I clearly understand what the matter is! It is the poisoning of over chlorine in pool water. If pool owners do not understand chlorine’s level, how will the lower chlorine in the pool? Chlorine is an essential and integral part of a pool. The healthy environment of the pool is maintained if its chemical balance is maintained.

And if the chlorine level is too high, then Mollie W.’s condition can happen to you. Indeed worried, there is no reason to worry. Controlling the chlorine levels in the pool is not very complicated. You can maintain proper pool chemistry and disinfect pool water by regularly adjusting chlorine levels.

Why does the level of chlorine in the pool increase?

Indeed, increasing the level of chlorine in the pool is not an unwanted thing, and it is a common problem. This condition made by pool shocking. The owners of the pool took the shock treatment in the pool before starting the pool. This shocking treatment gives to eliminates excess germs, algae, and bacteria from the pool. Excess chlorine is added to the pool water to carry out this process. Otherwise, bacteria and other parasites do not want to eradicate. If more tablets or chlorine carriers are added than needed during the pool’s shock treatment, it will also cause an increase the level of chlorine in the pool.

The use of cyanuric acid in the pool also strengthens the structure of chlorine. This acid has a strong chemical structure and protects the chlorine from the sun’s intense rays so that the chlorine structure does not break down easily. As a result, chlorine accumulates in the pool.

How to lower chlorine in the pool?

You can give your swimming pool several treatments to bring chlorine balance. There are many methods to reduce excess chlorine. However, I will provide you with some very effective and tried and tested methods. Hopefully, you will get the right process to reduce the chlorine level in your pool from those processes.

  1. Remove chlorine supply

If there is an excess of chlorine in your pool, you must immediately stop supplying chlorine. If the chlorine level in your pool does not increase, you should keep the chlorine’s correct concentration according to the water. You should remove the chlorine floater from your pool, and if you have a tablet in the skimmer, remove it from the skimmer as well because regular waves of chlorine continue to supply chlorine from the skimmer. In short, if the supply of chlorine in the pool stopped, it will not increase.

  1. Swimming in your pool

Swimming in the pool to release chlorine is a natural treatment. However, if the level of chlorine in your pool is slightly higher should go swimming. But if the level of chlorine is very high, it will not be of any use. In this case, it may harm the swimmers, and their bodies may become rash and swollen. So the pool has a small amount of chlorine, you can have a swimming party, which will also reduce the level of chlorine. It will be chemical-free and cost-effective at once. Since chlorine poisons the pool by removing enemy contaminants, it is essential to know its potential.

  1. Uses of Natural Sunshine

It is also a free treatment to reduce the level of chlorine in the pool. If it is possible to reach the sun in your pool, it will be very beneficial. The sun helps disperse the chlorine in your pool. If 2 to 3 hours of sunshine are allowed in the pool water, the pool water’s chlorine level reduces by about 80-90%. The sun’s ultraviolet rays pick up the chlorine from the pool and convert it into chlorine gas, a gas found in the atmosphere. However, before sunbathing in the pool must stop the chlorination. However, chlorination can re-introduce if it needs to sanitizing later.

  1. Add Hydrogen peroxide to the pool

Hydrogen peroxide is a powerful chlorine reducer. It is also called a powerful oxidizer for pools. It can break down the chemical structure of chlorine. It would be best to collect 35% food grade hydrogen peroxide; it works well in pool water. You can buy this oxidizer from your nearest store, and it is also relatively cheap. To use this chemical in the pool, you need to know the pool water’s pH level. If the pH level of the pool is less than 6.00, good results will not obtain. If it starts to act in the pool, you will see small gaseous bubbles come out in size.

  1. Add Sodium Thiosulfate

You can use sodium thiosulfate as an alternative if you cannot find a neutral product to reduce chlorine supply. Measure your pool water and chlorine levels before using it. If it does not react with chlorine, it exists in water. These chemicals can remove high levels of chlorine. Use a skimmer to apply it to the pool. Add the prescribed amount of sodium thiosulfate according to the amount of pool water and chlorine.

If you need to apply again after applying once, measure the level of chlorine also. Check the pH of the pool after reducing the chlorine with it. The chemical reaction caused by its application lowers the pool’s pH, which can cause the pool water to become acidic.

  1. Add Vitamin-C to the pool

Adding vitamin-c is an excellent treatment to reduce excess chlorine in the pool. Just as vitamin C can boost the human body’s immune system, so can the problem of chlorine in the pool. It can rapidly reduce very high energy chlorine, which cannot consolidate with other ingredients. It is not a harsh chemical to use on pool vinyl liners and fiberglass pool surfaces.

  1. Replace Pool Water

Changing pool water is a beneficial process for reducing chlorine. However, changing 1/3rd of the pool water will solve the problem. However, if the chlorine level is too much, the level should is reduced before replacing the pool water. After the water returns, re-test the water and take the classes of all the chemical elements.


Since chlorine is essential for the pool, regularly should test the pool water. Pool water should not be allowed to be acidic in any way. Chlorine equilibrium must achieve to not physically harm our children and guests while swimming in the pool. Not to give extra chlorine tablets while giving pool shock should take care.

According to the concentration of water should provide the treatment. Even then, if the level of chlorine in your pool rises, you can apply any one of the seven treatments mentioned above. Note that each chlorine reducing process is tested and can successfully reduce the excess of chlorine in your pool.
