What is the primary benefit of adding stabilizers like CYA to pool water?

The primary benefit of adding stabilizers like cyanuric acid (CYA) to pool water is to protect chlorine from sunlight. When chlorine is introduced to pool water, it can be rapidly broken down by the sun’s ultraviolet (UV) rays. By adding cyanuric acid, which acts as a stabilizer, you help shield the chlorine, allowing it to remain effective for a longer period of time. This is especially important for outdoor pools, where sun exposure is significant.

Maintaining chlorine levels is crucial for effective disinfection and sanitation of pool water, and without sufficient stabilizer, you would need to add chlorine more frequently, which can increase chemical costs and the effort required for pool maintenance. Therefore, the inclusion of cyanuric acid can lead to a more stable and efficient pool chemistry, ultimately helping to keep water clean and safe for swimmers.
