What is pool stabilizer?

Pool stabilizer, also known as cyanuric acid, is a chemical used to protect chlorine in swimming pools from breaking down quickly due to exposure to sunlight. Chlorine is commonly used as a disinfectant in pool water to kill bacteria, algae, and other microorganisms. However, chlorine can be degraded by sunlight, reducing its effectiveness in sanitizing the pool water over time.

Pool stabilizer helps to slow down this degradation process by absorbing ultraviolet (UV) rays from the sun, thereby preventing the chlorine from breaking down as quickly. This enables the chlorine to remain effective for a longer period, ensuring that the swimming pool water stays properly sanitized.

The ideal concentration of pool stabilizer in pool water typically ranges between 30 to 50 parts per million (ppm). Maintaining a stable level of pool stabilizer is important for proper chlorine performance and overall water quality in outdoor pools exposed to sunlight. By preventing the rapid depletion of chlorine, pool stabilizer helps to ensure that the pool water remains safe and enjoyable for swimming.

It's worth noting that pool stabilizer does not directly sanitize pool water on its own. Instead, it works by protecting the chlorine from breaking down, allowing it to effectively disinfect the water. Regular monitoring and maintenance of both pool stabilizer and chlorine levels are essential for ensuring proper sanitization and water balance in swimming pools.
