Pool cleaning is the process of maintaining a swimming pool to ensure it is safe and enjoyable for use. This involves removing debris, such as leaves and dirt, from the water's surface and the pool floor. Regular cleaning helps prevent algae growth and keeps the water clear. In addition to physical cleaning, pool maintenance includes checking and balancing the water chemistry. This ensures that the levels of chlorine, pH, and alkalinity are appropriate. Proper chemical balance is essential for preventing harmful bacteria and ensuring a safe swimming environment.
