Having a hard time keeping chlorine in the pool? Check your stabilizer levels. Unstabilized chlorine will burn out of a pool with less than 4 hours of exposure to sunlight. Cyanuric acid is needed to stabilize chlorine and should be approximately 20-40ppm in the water to ensure chlorine isn't burned off by the sunshine. However, never exceed 60ppm or it will bind the free chlorine in your pool and render it virtually useless.
