What Naturally Kills Algae in Pools?





Keeping your swimming pool sparkling clean involves more than just skimming off leaves and debris. Algae in pools can be a common problem for pool owners, and tackling it naturally is a top priority for those who prefer not to use harsh chemicals. In this article, we’ll explore some natural methods to eliminate algae in pools and keep them pristine.



Understanding Algae in Pools


Before we delve into how to naturally kill algae in pools, it’s important to understand what we’re dealing with. Algae are microscopic plants that can cause your pool to turn green, yellow, or even black. Algae in pools can make surfaces slippery, clog filters, and provide an ideal breeding ground for harmful bacteria.



Preventing Algae in Pools


Prevention is always better than cure, and this holds true for algae in pools. Here are a few preventative measures:


  • Maintain Proper Pool Circulation: Stagnant water is a breeding ground for algae. Ensure your pool pump and filter system are working effectively to keep water moving and make it less hospitable for algae growth.
  • Regularly Clean Your Pool: Brush and vacuum your pool weekly to remove any lurking algae spores. Pay attention to corners, stairs, and other areas where algae might start growing.
  • Test and Balance Your Pool Water: Regularly test your pool water and ensure it is properly balanced. Incorrect pH, alkalinity, or sanitizer levels can create the perfect environment for algae in pools.



Natural Methods to Eliminate Algae in Pools


If, despite your preventative efforts, algae have taken hold in your pool, don’t panic. Here are some natural methods to combat algae in pools:


  1. Sunlight: Algae aren’t fans of bright sunlight. Sunlight can help reduce the growth of algae in pools by breaking down the algae’s food source – chlorophyll.
  2. Baking Soda: Baking soda can help maintain the correct pH levels in your pool water, discouraging algae growth. It’s a natural and safe method, but remember, too much can be as harmful as too little, so be sure to get the balance right.
  3. Saltwater Pools: Saltwater pools can be an effective way to prevent algae growth. The salt cell in these pools produces natural chlorine that helps kill algae.
  4. Pool Plants: Some aquatic plants, like water lilies, help absorb nutrients that algae feed on, reducing their growth.
  5. Barley Straw: While not a quick fix, as the straw decomposes, it releases a chemical that interferes with algae growth.
  6. Diatomaceous Earth (DE) Filter: DE filters can help filter out algae from your pool water. They are made from fossilized remains of diatoms, a type of hard-shelled algae.


Regularly implementing these natural methods can help control algae in pools effectively.



The Aftermath: Treating Your Pool Post-Algae


Once you’ve successfully treated the algae in pools, there’s still work to be done. Algae spores are hardy and can easily return if you don’t follow up with proper pool maintenance.


  • Deep Clean Your Pool: Start by thoroughly vacuuming and brushing your pool. Pay special attention to corners, crevices, and other hard-to-reach areas where algae might hide.
  • Shock Your Pool: Even after naturally treating the algae, a shock treatment can help ensure that all remaining algae spores are eliminated. Choose a non-chlorine shock for a more natural option.
  • Clean Your Pool Filter: Your pool filter has likely collected a significant amount of algae during the treatment process. Clean it thoroughly to ensure it’s working at maximum efficiency.
  • Monitor Pool Chemistry: After an algae outbreak, keeping a close eye on your pool’s chemical levels is crucial. Test your pool water regularly to ensure that it’s properly balanced.
  • Prevent Future Algae Growth: Continue to employ the natural algae prevention methods listed above. Consistent pool maintenance is the most effective way to keep your pool algae-free.


Remember, the goal isn’t just to kill algae in pools, but to create an environment where they can’t thrive in the first place.


Algae in pools can be a challenge to deal with, but it’s a problem that’s definitely manageable. By understanding what causes algae and using the natural methods outlined in this article, you can keep your pool clean and safe.


Furthermore, the knowledge you’ve gained about how to naturally handle algae in pools can also be applied to other aspects of your home and garden. After all, the principles of balance, prevention, and natural treatment are universal.


While it may take some time and effort to learn to effectively manage algae in pools, the benefits are well worth it. You’ll have a healthier, more enjoyable pool and the peace of mind that comes with knowing you’re taking care of it in the most natural way possible.





Algae in pools can be a nagging problem, but with a little time and effort, it’s one that can be tackled naturally and effectively.
