How to Fix A Green Pool After Rain
After a heavy rainfall, your pool’s chemical balance can be disrupted, leading to altered pH levels, diluted chlorine, salt, and minerals. Moreover, leaves, dirt, and algae spores are carried into the water, which then decompose and deposit phosphates. These conditions, coupled with sunlight, create the ideal environment for algae and contaminants to thrive. The result? An overnight transformation of your pool into a murky green mess.
If your pool has turned green following a rainstorm, it’s likely due to algae growth in the water. To address this issue, we recommend visiting your local Poolwerx for a complimentary water test and obtaining Vitalyse Poly Plus Algaecide. If you prefer professional assistance, our Green to Clean Pool Service is also available.
How To Fix a Green Pool
Before beginning any post-rain storm pool cleaning, ensure you do the following:
Empty skimmer and pump baskets. If you don’t the accumulated debris in the pool will clog the baskets and reduce the flow of water.
Remove large debris and leaves from the water. They will influence the water chemistry of the pool and potentially stain your pool’s surface.
Test your pool water. Your local Poolwerx offers free water testing, and can provide personal recommendations to bring your pool back to health.
VITALYSE POLY PLUS ALGAECIDE
This works in conjunction with your chlorine, salt and minerals to quickly and more effectively kill the algae in your pool, bringing your pool back from green to clean.
Tips on using Vitalyse Poly Plus Algaecide:
Clean your pool up first. Organic material in the pool consumes algaecide, making it less effective.

Make sure you run your filter with the algaecide. This helps to disperse the algaecide and remove the suspended matter. Algaecides have little impact on stagnant water.
Never overdose your pool. Read and follow instructions on the label, and visit your local Poolwerx for a free water test to determine what dosage you should use.
Algae Growth in Pools:
It’s important as a pool owner to understanding the risks and the importance of preventing algae from growing in your pool.
Addressing algae growth is not only important for the aesthetics of your pool but also for the health and safety of swimmers. Algae can cause water to become cloudy, discolored, and develop an unpleasant odour. In addition, algae can make pool surfaces slippery and create breeding grounds for harmful bacteria. Swimmers may experience skin and eye irritation, and in severe cases, prolonged exposure to algae-infested water can lead to infections.
By understanding the different types of algae, recognising the contributing factors, and being aware of the potential health and aesthetic issues it can cause, pool owners can take proactive steps to effectively prevent and treat algae growth. Regular maintenance, proper water chemistry, and appropriate sanitation practices are essential in keeping your pool algae-free and a safe and inviting swimming environment.
Steps to Remove Algae After Rain and Restore Water Clarity
Dealing with algae in your pool after a rainstorm can be a frustrating experience. However, with the right approach and prompt action, you can effectively eliminate algae and restore clarity to your pool. Follow these steps to get rid of algae in your pool after rain:
-
Examine the pool water to determine the severity of the algae growth. This will help you gauge the appropriate treatment.
-
Using a skimmer net, remove any debris, leaves, or visible algae from the pool surface. Brush the pool walls and floor to loosen and dislodge any clinging algae.
-
Use a reliable pool water testing kit or visit your local Poolwerx for a complimentary water test. This will help identify any imbalances in pH levels and chlorine concentration.
-
Choose a suitable pool shock treatment and follow the manufacturer’s instructions to shock the pool. This process introduces a high dose of chlorine to kill the existing algae and restore chemical balance.
-
Select a quality algaecide designed to target the specific type of algae in your pool. Follow the recommended dosage instructions and distribute it evenly throughout the pool.
-
Keep the pool filter running continuously to ensure proper circulation. This will help filter out dead algae and prevent its re-growth.
-
Take proactive steps to prevent future algae growth. This includes proper pool maintenance, regular skimming and cleaning, maintaining adequate sanitiser levels, and ensuring proper water circulation.
By following these steps, you can effectively get rid of algae in your pool after rain and maintain a clean, clear, and inviting swimming environment.
How to Treat My Saltwater Pool After Rain?
Saltwater pools offer their own set of challenges when it comes to preventing algae growth. To keep your saltwater pool free from algae, maintain proper salt levels recommended by the manufacturer, monitor and adjust pH levels, brush and vacuum your saltwater pool regularly, and keep the filter system running effectively.
Taking these steps will help keep your saltwater pool free from algae and ensure a clean and enjoyable swimming experience.
Cleaning Your Pool After Rain
Don’t let algae take control of your pool after a rainstorm. Act promptly to prevent health risks and maintain a pristine swimming environment. By promptly skimming and brushing, testing and balancing water chemistry, shocking the pool, adding algaecide, running the filter, and taking preventive measures, you can successfully eliminate algae and restore water clarity.
