Why Did Your Pool Turn Green?

Are you frustrated with your once crystal-clear pool now looking like a pond? Well, don’t worry. You’re not alone. A green pool is a common problem that many pool owners face, especially during the warmer months. So, why did your pool turn green?

The primary reason behind a cloudy pool is poor maintenance or lack of pool cleaning. If you neglect your pool maintenance service, the water can quickly become a breeding ground for algae, quickly turning a sparkling blue pool into a murky green mess. Algae thrive in warm water with little to no chlorine, so it’s essential to ensure that your pool water stays balanced with regular pH testing and proper chemical treatment.

A malfunctioning filter or pool pump is another common reason for a green pool. Your filter’s primary function is to remove contaminants from the water while the pump circulates it. If either of these components fails, the water will stagnate, and algae growth will skyrocket.

Steps to Clean a Green Pool:

You might face a green pool if you’ve been neglecting your pool maintenance service. But fear not. Let us walk you through the essential steps you need to take to get your pool back to its crystal-clear state.

Clean Existing Debris and Algae

The first and most critical step is to remove any debris or pool algae accumulated in your pool. If the water is extremely murky, use a skimmer to remove large items. For any residual dead algae or fine debris, use a pool brush to scrub the pool walls and floor.

Shock Your Pool Water

The next step is to use a heavy chlorine dosage to shock your pool green water. This is crucial to kill off any thriving bacteria in the stagnant water. Use a high-quality pool shock compatible with your pool’s chemical system, and distribute it evenly across the pool’s surface. These are available in most pool stores, and the directions of how much shock is needed are usually mentioned on the package. Ensure the pool covers are removed before you hit the pool, or the shock treatment will be partially ineffective.

Adjust Pool Chemical Levels

After shocking, it is crucial to measure the pH and alkalinity levels of your pool water using a test kit. Maintaining an ideal pH range of 7.2-7.8 is essential for optimal pool conditions. Should your pH levels be too low, simply adding sodium carbonate will help raise them. Conversely, if they are too high, you can easily lower them by adding muriatic acid.

Run the Pool Filters

The filters of your pool are the powerhouse of the cleaning process. Once the shock treatment and chemical adjustments have been made, let your pool filter run for several hours. This will remove any excess chlorine and debris disturbed by the shock treatment. Keep the filter system running for several days to filter any remaining algae or bacteria out of your pool.

Keep Up with Proper Pool Maintenance

Regular pool maintenance is essential to keep your pool clean and functioning correctly. You don’t want to repeat the same process of cleaning again and again. You should maintain your pool consistently to avoid the occurrence of any further wastewater pool. If you’ve tried to fix the problem yourself and still have a green pool, it might be time to call in the professionals. Don’t let your green pool ruin your summer fun.

How Long Does It Take to Clean a Green Pool Water?

Cleaning a green pool can be daunting, but the result is worth it. However, one question often on every pool owner’s mind is how long it takes. Unfortunately, this question has no clear-cut answer, as it depends on various factors.

Firstly, the severity of the algae growth in your pool will determine the time taken to clean it. If the algae have been allowed to grow for a long time, then killing algae will take longer. Secondly, the size of your pool also plays a role in determining the cleaning time. Larger swimming pools require more effort and time to clean than smaller ones.

Moreover, the method used to clean your pool will also impact the duration. For instance, manual cleaning using a brush and net may take longer than chemical treatments. However, chemical treatments also require time to work effectively, and it is recommended not to swim in the pool for some time.

The time it takes to fix green pool water varies depending on the severity of the algae growth, pool size, and the method used. Therefore, it is crucial to seek professional help if you need are overwhelmed. Remember, proper maintenance can prevent the growth of algae and ensure your pool remains crystal clear throughout the year.


Green pool water can be incredibly frustrating and defeating, but it doesn’t have to be. With the help of some simple steps, you can get your pool looking crystal-clear in no time. Just remember that preventing a green swimming pool from happening again is key! Keep your pH levels balanced, test your water regularly, keep up with any necessary repairs or maintenance on time, and remember to use shock treatments and pool chemicals to prevent algae growth. With the right supplies and know-how behind you, cleaning and maintaining your pool will go smoothly again in no time.
