Do solar bed covers attract algae growth, and how can I prevent it?

While solar bed covers themselves do not inherently attract algae, the conditions they create can sometimes contribute to its growth if not properly managed. Buyers frequently ask about this, especially in warmer climates. The main reason is that solar covers increase water temperature, which algae thrives in. They also block some sunlight, but enough light often penetrates to support photosynthetic organisms like algae, particularly if your sanitizer levels are low.

To effectively prevent algae, consistent pool chemistry is key. Maintain your chlorine or bromine levels within the recommended range for your pool type. Regularly test your water for pH, alkalinity, and calcium hardness, as imbalances can make your sanitizer less effective. Shock your pool as needed, especially after heavy use or prolonged warm weather. Some pool owners, based on thousands of verified purchases, find it beneficial to run their pump and filter for longer durations when the cover is on, ensuring better water circulation and filtration. Brushing your pool walls weekly also helps dislodge any clinging algae spores before they can multiply. If you do notice early signs of algae, address it immediately with an algaecide appropriate for your pool type. Many users also suggest periodically cleaning the underside of the solar cover itself with a mild solution and rinsing thoroughly to remove any clinging organic matter that could provide a breeding ground for algae spores.
