The Pool Breeze Optimight tablets are the first step in the Pool Breeze Optimight 3-Step System. These slow dissolving tablets will help sanitize your pool water, without adding extra unnecessary stabilizer (CYA) that could throw off the chemistry of your water. Safely boost the chlorine in all pool systems.

Note: For every 10 ppm Free Chlorinne (FC) added by this Cal-Hypo product, it also increases Calcium Hardness (CH) by 8 ppm.”
