What Causes Yellow Algae on Pool Walls?
Yellow algae, also known as mustard algae, can be a common problem for pool owners. It can be frustrating to deal with, especially when it keeps coming back. Understanding what causes yellow algae to form in the first place is key to getting rid of it for good. One of the main causes of yellow algae is poor water circulation. When water is stagnant, it creates a breeding ground for algae to grow. It can also be caused by poor filtration, lack of maintenance, or an imbalance in pool chemistry.
Another common cause of yellow algae is inadequate chlorine levels. Chlorine is essential for killing and preventing algae growth, so if there isn’t enough in the pool, algae can easily take hold. In some cases, it can also be caused by pool toys or floats that have been left in the water for too long, or by swimmers who haven’t properly rinsed off before entering the pool.
Finally, high temperatures and prolonged exposure to sunlight can contribute to the growth of yellow algae. If your pool water is consistently warm and the sun is shining down on it for most of the day, it can create the perfect environment for algae to thrive.
Now that you know what causes yellow algae to form, it’s time to take action and get rid of it. Keep reading for our step-by-step guide on how to remove yellow algae from pool walls and prevent it from coming back.
Insufficient Chlorine Levels
-
Chlorine is essential in preventing algae growth in your pool. If your pool’s chlorine levels are too low, it can lead to the growth of yellow algae. Ideally, your pool’s chlorine levels should be between 1-3 ppm (parts per million).
-
Regularly test your pool’s chlorine levels to ensure they are within the recommended range. You can use a test kit or test strips to measure the levels. If the levels are low, add chlorine to your pool to bring it back to the recommended range.
-
Shocking your pool can also help remove yellow algae caused by insufficient chlorine levels. Shocking involves adding a large amount of chlorine to your pool to raise the levels and kill any algae present. Follow the instructions on the shock product you are using.
Keeping your pool’s chlorine levels within the recommended range is crucial to preventing the growth of yellow algae on your pool walls.
High pH and Alkalinity Levels
Another common cause of yellow algae growth in pools is high pH and alkalinity levels. The recommended pH level for a pool is between 7.2 and 7.8, while the recommended alkalinity range is between 80 and 120 parts per million (ppm). When the pH and alkalinity levels are high, the water becomes basic and less acidic, creating a favorable environment for yellow algae to thrive.
Additionally, high pH levels can also lead to the formation of calcium carbonate, which can create a breeding ground for yellow algae. This is particularly common in areas with hard water, which contains high levels of dissolved minerals.
To prevent yellow algae from growing due to high pH and alkalinity levels, it’s important to regularly test the water and adjust the pH and alkalinity levels accordingly. Using a pH decreaser and alkalinity increaser can help bring the levels back to the recommended range.
Identifying Yellow Algae vs. Green Algae
Algae Growth: Algae is a common problem in swimming pools and can come in various colors, including green, yellow, and black. Green algae is the most common type, while yellow algae is less common but still prevalent. Identifying the type of algae in your pool is crucial for effective treatment.
Appearance: Yellow algae are also known as mustard algae because of their yellow-green color. They typically form in small, isolated spots on the walls, steps, or other shady areas of the pool. Green algae, on the other hand, are bright green and can quickly spread throughout the entire pool.
Texture: Yellow algae have a slimy texture and can be challenging to remove from pool surfaces. They are often mistaken for sand or dirt deposits. In contrast, green algae have a more granular texture and are easier to brush off surfaces.
Treatment: Both yellow and green algae can be treated with a shock treatment of chlorine or algaecide. However, yellow algae are more resistant to treatment than green algae and may require additional steps, such as brushing the affected areas or using a specialized algaecide formulated for yellow algae.
Prevention: The best way to prevent algae growth in your pool is to maintain proper water chemistry and sanitation levels. Regularly test and adjust the pH, alkalinity, and chlorine levels, and keep the pool clean and well-circulated.
