Regular brushing of pool surfaces is highly recommended primarily to prevent algae buildup and ensure cleaner water. Algae can grow in areas where circulation is poor, such as corners, steps, and around features like ladders and lights. By brushing the surfaces, you disrupt algae growth, making it more difficult for it to take hold. This process also helps to remove dirt and debris that may have settled on the pool surfaces, contributing to the overall cleanliness of the water.

Moreover, brushing assists in ensuring that the chemicals added to the pool are effective. When surfaces are brushed, contaminants are loosened and can be more effectively removed by the pool's filtration system. This helps maintain balanced water chemistry, which is vital for a safe and enjoyable swimming environment.

While other options address different aspects related to pool maintenance, they do not directly connect to the core purpose of regular brushing, which is primarily preventative in terms of algae growth and enhancing the cleanliness of the pool.
