Stabilizer, chemical name: Cyanuric Acid, acts like a shield which prevents the sun from dissipating the chlorine from your pool. It is measured in ppm and it’s optimum range is between 30-50 ppm. Some pools may require more or less of this chemical depending on the other chemistry elements in your water or UV exposure. If your reading is too low, your chlorine stands to burn off prematurely; if your reading is too high, you risk getting ‘chlorine lock’, where the chlorine in your water is rendered ineffective.
*Please read all labels before adding any chemical to your pool, follow all safety instructions and consult a pool professional if you have any questions.
