Pools are a great way to spend your weekends and summers. They offer a refreshing way to cool off, relax and have fun with family and friends. However, there are times when you might find your pool turning green despite having high levels of chlorine. This can be frustrating and confusing, especially if you have been diligent in maintaining your pool. In this article, we will explore the reasons why your pool may turn green despite having high levels of chlorine.
Before we delve into the reasons, it is essential to understand the role of chlorine in keeping your pool clean and clear. Chlorine is a chemical that is widely used in swimming pools to kill off bacteria, viruses, and other microorganisms that may be present in the water. It works by breaking down the cell walls of these microorganisms, rendering them harmless. Chlorine is also responsible for oxidizing organic matter such as sweat, urine, and other bodily fluids that may end up in the pool. In short, chlorine is critical in maintaining a safe and healthy swimming pool environment.
Now, let us explore the reasons why your pool may turn green despite having high levels of chlorine.
1. Algae growth – Algae are microscopic plants that can grow in your pool if conditions are favorable. They thrive in warm, stagnant water and can quickly spread if not treated promptly. Algae can turn your pool green, especially if you have a high concentration of green algae. Although chlorine can kill off algae, it may not be effective if the algae have formed a protective layer on the pool surface. In this case, you may need to shock your pool with a high dose of chlorine or use an algaecide to get rid of the algae.
2. Low pH levels – pH is a measure of the acidity or alkalinity of your pool water. The ideal pH range for a swimming pool is between 7.2 and 7.8. If your pool water is too acidic (low pH), it can cause the chlorine to become less effective. This means that despite having high levels of chlorine, it may not be able to kill off bacteria and other microorganisms. Low pH levels can also cause skin and eye irritation in swimmers. To address this issue, you can use a pH increaser to raise the pH levels of your pool water.
3. High Cyanuric Acid (CYA) levels – Cyanuric Acid is a chemical that is added to swimming pools to stabilize the chlorine. It helps to protect the chlorine from being broken down by the sun’s UV rays, thereby prolonging its effectiveness. However, if the CYA levels in your pool are too high, it can cause the chlorine to become less effective. This means that despite having high chlorine levels, it may not be able to kill off bacteria and other microorganisms. To address this issue, you can drain some of the pool water and add fresh water to dilute the CYA levels.
4. Poor circulation – Your pool’s circulation system plays a vital role in maintaining a clean and clear swimming pool. If your pool’s circulation system is not working correctly, it can cause the water to become stagnant, leading to the growth of algae and other microorganisms. Poor circulation can also cause the chlorine to become less effective. To address this issue, you may need to check your pool’s pump and filter system to ensure that they are working correctly.
In conclusion, a green pool despite having high levels of chlorine can be frustrating and confusing. However, understanding the reasons behind it can help you address the issue promptly. If you are unsure, you can always seek the help of a professional pool maintenance company. Remember, a clean and clear pool is not only more enjoyable to swim in, but it is also safer and healthier for you and your family.

Frequently Asked Questions about Why Is My Pool Green But Chlorine Is High?
1. What causes a green pool?
A green pool is usually caused by the growth of algae in the water. Algae can grow rapidly in warm and humid weather, especially if the pool is not properly maintained or if the water chemistry is not balanced.
2. Why is my pool green even though I have a high level of chlorine?
Even though you have a high level of chlorine in your pool, it may not be effective in killing the algae if the pH and alkalinity levels are not balanced. A high pH level can reduce the effectiveness of chlorine in killing algae, while a low pH level can cause the chlorine to dissipate too quickly.
3. Can I still swim in a green pool with high chlorine levels?
Swimming in a green pool with high chlorine levels is not recommended as it can cause skin and eye irritation, and even respiratory problems. It is best to wait until the pool is properly treated and the water is clear before swimming.
4. How do I fix a green pool with high chlorine levels?
To fix a green pool with high chlorine levels, you need to balance the water chemistry by testing and adjusting the pH and alkalinity levels. You may also need to shock the pool with a higher dose of chlorine to kill the algae. It is recommended to seek advice from a professional pool service to ensure proper treatment.
