What Causes Green Pool Water After Rain?
The first step in solving any problem is understanding its root cause. In this case, a few factors can contribute to green pool water after rain.
1. Rainwater Contamination
Believe it or not, rainwater is not entirely pure and can contain various pollutants and contaminants such as dirt, debris, pollen, and bacteria. When heavy rainfall occurs, the excess water can overflow from your pool and bring these impurities along with it, causing your pool water to turn green.
2. Increased pH and Alkalinity Levels
When rainwater enters the pool, it can cause a rise in pH and alkalinity levels, making the water more basic. This can create an ideal environment for algae growth, leading to that dreaded green hue in your pool.
3. Nutrient-Rich Environment
Algae need nutrients to thrive, and rainwater can provide an abundance of them in the form of nitrates and phosphates. These nutrients, warm temperatures, and sunlight create the perfect breeding ground for algae growth.
Now that we know why our pool water turns green after rain let’s get into the steps to fix it.
10 Easy Steps on How to Fix Green Pool Water After Rain
Step 1: Test Your Pool Water
Before adding any chemicals, it’s crucial to test your pool water using a pool test kit. This will give you an accurate reading of your pH, alkalinity, and chlorine levels. It will also help you determine the amount of shock and algaecide needed to fix the green pool water.
Step 2: Skim and Brush Your Pool
Begin the process by removing any visible debris, leaves, or algae from the surface of your pool using a skimmer net. This not only ensures a cleaner environment but also makes the later steps of the process more effective.
After skimming, it’s time to brush the walls and floor of your pool. Use a pool brush to scrub and loosen any algae clinging to these surfaces. This step is crucial because it prepares the algae for the upcoming treatment, making it more susceptible to the chemicals you will add next.
Step 3: Shock Your Pool
Now, it’s time to shock your pool. Shocking, also known as super-chlorinating, is a process to kill bacteria and algae by adding high levels of chlorine. Follow the instructions on your pool shock package for the recommended dosage, usually based on your pool size and the severity of the algae problem.
Ensure that the shock is distributed evenly across your pool, focusing mainly on areas where algae growth is most prevalent. Remember, it’s best to shock your pool in the evening or at night to maximize its effectiveness and avoid the chlorine being burnt off by sunlight. Allow the shock treatment to work overnight for best results.
Step 4: Add Algaecide to Your Pool
After shocking, adding an algaecide to your pool is next. An algaecide is specifically designed to kill and prevent future algae growth. It breaks down the algae’s outer protective layer, causing it to die. Follow the instructions on the algaecide packaging for the correct dosage.
Once added, ensure the pool pump runs to circulate the algaecide thoroughly throughout the pool. Like shocking, it’s best to add the algaecide at night or in the evening to avoid sunlight that can reduce its potency. Let it work overnight to ensure maximum effectiveness.
Step 5: Run Your Pool Pump
Once the algaecide has been added, you should run your pool pump for at least 24 hours. This is crucial for circulating the chemicals, ensuring they reach all pool areas and effectively combat the algae. During this time, avoid swimming in the pool to let the chemicals do their job. This also helps filter out dead algae and other debris from your pool. After 24 hours, check the pool water. You may need to repeat the shock and algaecide treatment if it’s still green.
Step 6: Test and Balance Your Pool Water
After the shock and algaecide treatment, it’s time to test your pool water again. Here, you’re looking for your pH, alkalinity, and chlorine levels to be in the correct range. If the pH and alkalinity levels are too high, you can lower them by adding a pH reducer. If the levels are too low, add a pH increase.
Similarly, ensure that your chlorine levels are optimal. If the levels are too high, let your pool sit without the pool cover to let the excess chlorine evaporate. If the levels are too low, add more chlorine per the requirements. Remember, balanced pool water is key to preventing future algae blooms.
Step 7: Vacuum Your Pool
After the chemical treatments, vacuum your pool to remove dead algae and residual debris. Algae are microscopic and may not always be caught by the pool filter, so vacuuming ensures that any remnants are suctioned out of the pool. You may choose to vacuum manually or use an automatic pool vacuum, depending on your pool size and preference.
Cover all pool areas, including the floor, steps, and corners. After vacuuming, properly dispose of the collected debris to avoid any potential recontamination.
Step 8: Clean and Backwash Your Filter
Now that the pool has been thoroughly cleaned, it’s time to focus on the filter. Whether you have a cartridge, sand, or diatomaceous earth filter, it’s crucial to clean and backwash it after a heavy algae bloom. Backwashing involves running pool water in reverse through the filter to flush out any trapped debris or dead algae. Follow the manufacturer’s instructions for your specific filter model.
After backwashing, remove the cartridge and clean it with a hose if you have a cartridge filter. If the cartridge appears damaged or worn out, consider replacing it. After backwashing sand or diatomaceous earth filters, you may need to add more sand or diatomaceous earth. Cleaning your filter aids in maintaining clear, algae-free pool water.
Step 9: Regularly Monitor Your Pool
Regular monitoring is essential to prevent future occurrences once you’ve successfully cleared your pool of green algae and restored its clarity. Implement a routine of checking the pool’s chemical levels at least once a week. Also, watch the water clarity and look for any signs of new algae growth.
Algae can multiply quickly, so addressing any new growth immediately is critical. Remember, it’s easier to prevent algae from growing than it is to remove it once it has bloomed. Regular maintenance and observation will go a long way towards keeping your pool clear and inviting.
Step 10: Invest in a Pool Cover
Investing in a pool cover is the final step in maintaining a clear, algae-free pool. When your pool is not in use, especially during rainy weather or off-season months, a pool cover can prevent an influx of debris, organic material, and algae spores, contributing to algae growth. Furthermore, it reduces sunlight penetration, which can promote algae growth. Ensure the pool cover fits securely and covers the entire pool surface for maximum protection.
By following these steps and incorporating regular pool maintenance into your routine, you can effectively handle algae blooms and prevent them from occurring in the future. With clean and clear water, your pool will always be ready for a refreshing dip whenever you desire.
