  • DiChlor: Granular with cyanuric acid
  • Bromine: 1” tabs. Would be better if the pH is stable
  • Cyanuric acid: Liquid or dry stabilizer. It helps protect chlorine from damage by UV rays.


These act as the secondary sanitizers for your swimming pools. To kill algae, or to stop algae and bacteria from growing, best to use every few weeks

  • Calcium Hypochlorite: helps to sanitize pool water quickly, boost chlorine level, and kill algae. Better with a low pH level – 7.2.
