Five Easy Steps for Crystal Clear Water with That Pool Shop’s How To Fix A Green Pool Guide!
Without much use over the winter months, your swimming pool’s water may have turned green. Don’t worry, though, because with the right knowledge, tools, and a few simple steps, it’s easy to bring your pool water back to its clear and sparkling state. In this comprehensive guide, we will walk you through the process of fixing a green pool, offering valuable insights and answering frequently asked questions along the way. Let’s dive in!
Why do pools turn green?
The most common reason pool water turns green is due to the growth of algae. Algae can flourish rapidly, especially in hot weather, often surprising pool owners overnight during the warmer months. This issue typically arises from an imbalance or lack of chlorine in the water. In order to effectively address a green pool, it’s crucial to follow a systematic approach.
What tools and materials do I need to fix a green pool?
Before we begin, let’s gather the necessary tools and materials for the task at hand. You will need:
- Acid pH decreaser
- Algaecide
- Flocculent
- Chlorine or super shock
Step 1: Balancing the pH Level
To begin the process of fixing a green pool, it’s important to address the pH level of the water. Lowering the pH level creates an environment where chlorine can more effectively eliminate algae. You can easily achieve this by using acid or pH decreaser.
Step 2: Super Shock Chlorination
Next, it’s time to shock your pool with chlorine to eliminate organic substances and neutralise any potential threats. Super shock chlorine products offer higher chlorine levels that effectively combat algae and other unwanted elements. Follow the instructions on your preferred product, such as That Pool Shop’s chlorine shocks for optimal results. This step is especially crucial after heavy rain or when your pool has experienced a high level of usage.
Step 3: Enhance Water Clarity with Flocculent
For sparkling clear water, it’s important to break up the algae in your pool for easy vacuuming. Using a high-potency flocculent helps achieve this while improving the performance of your pool filter. Refer to the packaging of a trusted flocculent product, such as That Pool Shop’s liquid flocculent and clarifiers, for the appropriate dosage based on your pool’s needs.
Step 4: Algae Elimination with Algaecide

To effectively eradicate algae or other life forms present in your green pool, employ a high-strength algaecide. Consult the product packaging for accurate dosage levels. For reliable algaecide options, consider That Pool Shop’s algaecides to combat and prevent future algae growth.
Step 5: Regular Maintenance and Servicing
Once you’ve successfully treated your green pool, it’s vital to maintain its health and prevent future issues. Regular pool maintenance and servicing play a significant role in keeping your pool water clear and inviting. Consider scheduling routine maintenance with That Pool Shop’s professional pool servicing in SA for expert care and optimal pool performance.
By following these 5 simple steps, you can transform your green pool into a refreshing oasis. Remember to prioritize proper water balance, shock chlorination, flocculent treatment, algaecide application, and ongoing maintenance for long-lasting results.
