Swimming pools are a great way to beat the summer heat and relax with friends and family. However, owning a pool comes with its own set of challenges, one of which is keeping the water and walls clean. It’s not uncommon for pool owners to notice green algae growth on the walls of their pool while the water remains clear. This can be frustrating and confusing, as one would expect the entire pool to be affected if there was an algae problem. In this article, we’ll explore the reasons behind this issue and offer some solutions to keep your pool walls and water clean.
What Causes Green Algae Growth on Pool Walls?
Algae is a common problem in swimming pools, and it can grow quickly if conditions are right. Algae spores can enter your pool through wind, rain, or even swimmers who have recently been in a contaminated body of water. Once the spores find a suitable environment, they can grow and spread rapidly. Algae thrives in warm, stagnant water with high levels of sunlight and nutrients. If your pool is not properly maintained, it can become a breeding ground for algae.
When algae growth occurs on the walls of your pool, it’s usually due to poor circulation or filtration. Algae can attach itself to the walls and grow in areas where the water is not circulating properly. This can happen in areas of the pool where there is low water flow, such as dead spots or corners. Additionally, if your pool’s filtration system is not working correctly, it can’t remove the algae from the water, allowing it to grow and spread.
How to Get Rid of Algae on Pool Walls
If you notice green algae growth on your pool walls, it’s important to take action immediately to prevent it from spreading. Here are some steps you can take to get rid of algae on pool walls:
1. Brush the Walls
The first step to removing algae from pool walls is to brush them thoroughly. Use a pool brush to scrub the walls and floor of your pool, paying extra attention to areas where algae is growing. Brushing will help to loosen the algae from the walls, making it easier to remove.
2. Shock Your Pool
The next step is to shock your pool with a high dose of chlorine. This will help to kill any remaining algae spores in the water and prevent new growth from occurring. Follow the instructions on your pool shock product carefully, and be sure to keep swimmers out of the pool until the chlorine levels return to safe levels.
3. Adjust Your Water Chemistry
Proper water chemistry is essential for maintaining a clean and healthy pool. If your pool’s pH, alkalinity, or chlorine levels are out of balance, it can create an environment that is conducive to algae growth. Test your water regularly and make adjustments as needed to keep your water chemistry in check.
4. Improve Circulation and Filtration
To prevent algae from growing on your pool walls in the future, you’ll need to improve circulation and filtration. Make sure your pool’s circulation system is working correctly, and consider adding extra jets or a booster pump to improve water flow in problem areas. Additionally, make sure your pool’s filter is clean and functioning properly. A dirty or clogged filter won’t be able to remove algae from the water effectively.
How to Prevent Algae Growth on Pool Walls
Prevention is always better than cure when it comes to pool maintenance. Here are some steps you can take to prevent algae growth on your pool walls:
1. Maintain Proper Water Chemistry
As mentioned earlier, proper water chemistry is essential for maintaining a clean and healthy pool. Make sure to test your water regularly and adjust your pH, alkalinity, and chlorine levels as needed. Keeping your water chemistry in check will help to prevent algae growth.
2. Clean Your Pool Regularly
Regular cleaning is important to prevent algae growth in your pool. Use a pool skimmer to remove debris from the surface of the water, and vacuum the pool regularly to remove any dirt or debris that has settled on the bottom. Additionally, make sure to brush your pool walls and floor regularly to prevent algae from attaching itself to the surfaces.
3. Improve Circulation and Filtration
Proper circulation and filtration are key to preventing algae growth in your pool. Make sure your pool’s circulation system is working correctly, and consider adding extra jets or a booster pump to improve water flow in problem areas. Additionally, keep your pool’s filter clean and replace it as needed to ensure it is functioning properly.
4. Use Algaecide
Algaecide is a chemical that can be added to your pool to prevent algae growth. There are several different types of algaecide available, so make sure to choose one that is suitable for your pool. Follow the instructions carefully when using algaecide, and be sure to test your water regularly to ensure it remains in balance.
Conclusion
Green algae growth on pool walls can be frustrating, but it’s a common problem that can be prevented with proper maintenance. Regular cleaning, proper water chemistry, and good circulation and filtration are key to keeping your pool walls and water clean and healthy. If you do notice algae growth on your pool walls, take action immediately to prevent it from spreading. By following these tips, you can enjoy a clean and sparkling pool all summer long.
