What Causes High Chlorine Levels
High chlorine levels can be a real problem in pools. Sometimes, it's simply a matter of adding too much chlorine to the water. This can happen when adding shock to the water or putting in too many chlorine tablets in the skimmer.
Using too much liquid chlorine or chlorine tablets can also lead to high chlorine levels. Not using a chlorine stabilizer is another common mistake that can cause this issue.
Your pool's lack of sun exposure can also cause chlorine levels to stay high. This is because chlorine isn't breaking down properly in the absence of sunlight.

- Vomiting
- Burning nose, throat, eyes
- Coughing
- Difficulty breathing
These symptoms can be a sign of chlorine poisoning, which can happen in pools with extremely high chlorine levels. If you experience any of these symptoms, get out of the pool and rinse off with clean water as soon as possible.
Short Term: Irritation
High chlorine levels in a pool can cause immediate irritation, making it uncomfortable to swim. You might experience eye irritation, even if you keep your eyes closed underwater, due to chloramine in the water mist.
Chlorine and chloramine can also dry out your hair and nails, making them feel brittle and rough. This can be a nuisance, especially if you have long hair.
The higher the chlorine levels, the more intense the irritation will be. You might feel like you're in a harsh environment, which can be unpleasant and even painful.
Here are some common symptoms of chlorine irritation:
- Eye irritation
- Lung irritation
- Skin irritation
- Dry, brittle hair and nails
These symptoms can be uncomfortable and even painful, making it difficult to enjoy your swim. It's essential to maintain proper chlorine levels in your pool to avoid these issues.
Brittle Hair, Nails, and Skin
High levels of chlorine in your swimming pool can cause your hair, skin, and nails to become brittle. This is because chlorine strips your body of the protective oils it needs to maintain a moisture barrier.
Dry skin is a common symptom, as the skin's natural moisture is stripped away. Hair and nails become brittle and prone to breaking.
Those with skin conditions like eczema may experience worse symptoms, as high chlorine levels can trigger skin irritation and increase the likelihood of flare-ups.
If you colour your hair blonde, you may notice a green tint from excessive chlorine levels. This is often a sign of high copper levels in the pool, which can be indirectly related to high chlorine levels.
To minimize the risks, keep the area well-ventilated, especially if you're adding undiluted chlorine solution to the pool. This can reduce the chances of a burn in case of a spill or leak.

5 Ways to Lower Levels
Lowering chlorine levels in your pool can be a simple process. If your chlorine levels are too high, there are some easy ways to bring them back down.
A few hours of direct sunlight can reduce your chlorine levels by up to 90 percent. Just be sure to check your chlorine levels to avoid going below the recommended range of 1 to 3 parts per million.
Adding a chlorine neutralizer, like Sodium Thiosulfate, is one of the quickest ways to lower chlorine levels. Be careful not to overdo it, as this can lower your pH levels significantly.
Letting the sun burn off some of the chlorine is a free and easy solution. However, if you use cyanuric acid to stabilize your chlorine, this method may not be as effective.
Adding a chlorine neutralizer will also remove bromine from your pool water. This is worth considering if you have both chlorine and bromine in your pool.
Lowering the Level
You can lower the chlorine level in your pool using various methods. One of the quickest and best fixes is to add a chlorine neutralizer. This can be done by adding sodium thiosulfate (THIGH-A SULFATE), which removes chlorine and bromine from swimming pool water.
Direct sunlight can also help reduce chlorine levels by up to 90 percent, but this may not work as well if you use cyanuric acid to stabilize your chlorine. It's essential to ensure your chlorine levels don't drop below 1 to 3 parts per million.
To avoid overdoing it, start by adding smaller amounts of sodium thiosulfate and test your chlorine levels as you go. Be sure to test your pH levels after you're done, as this chemical can significantly lower your pH.
Here are some ways to lower chlorine levels in your pool:
- Use a chlorine feeder or automatic chlorinator that dispenses chlorine gradually and consistently.
- Follow manufacturer instructions when adding pool chemicals, including chlorine.
- Maintain your pool's filtration and circulation systems to ensure even chlorine distribution.
- Consider using a chlorine stabilizer, aka cyanuric acid, to slow the process of chlorine breaking down.
Remember, preventing high chlorine levels is easier than dealing with them afterward. Regular maintenance and following guidelines can help you achieve a safe and healthy pool environment.
Testing and Safety
You should test your pool's chlorine levels at least once a week, especially during swimming season, to maintain the proper balance.
Regular testing is essential to ensure the chlorine level is safe for swimming. You can use pool test kits or consult a professional pool service for accurate testing and guidance.
Swimming in a pool with 10 ppm chlorine is not recommended, as it can cause eye irritation, skin problems, and respiratory issues. The safe chlorine level for swimming pools is generally between 1 ppm and 4 ppm.
You should wait until all your levels, like pH and chlorine, are in range before anyone gets in the water. This ensures a safe and healthy swimming experience.
The maximum recommended chlorine level in a swimming pool is 4 ppm, but it's essential to maintain a level that's sufficient to kill bacteria and algae. Factors like sunlight, pool usage, and stabilizer level can affect how quickly chlorine breaks down.
Symptoms and Risks
