Key Takeaways:

1. Types of Chlorine:
   • Stabilized Chlorine: Contains stabilizer (cyanuric acid) which acts as a sunscreen for chlorine, protecting it from sunlight. Common forms include:
     • Trichlor Tablets: 3-inch or 1-inch tablets, usually placed in chlorinators, floaters, or skimmers.
     • Dichlor Granular: Granular form that can be diluted in a bucket or directly added to the pool.
   • Unstabilized Chlorine: Does not contain stabilizer, allowing chlorine to work more efficiently in shaded or indoor pools. Common forms include:
     • Calcium Hypochlorite (Cal Hypo): Available in granular or tablet form.
     • Liquid Chlorine: Also known as liquid shock, typically 12% strength, higher than household bleach.
2. Stabilizer Levels:
   • Optimal Range: Maintain stabilizer levels between 30-40 ppm.
   • Too Low: Chlorine is quickly burned off by the sun.
   • Too High: Chlorine effectiveness decreases.
3. Chlorine Products:
   • Stabilized Chlorines: Ideal for pools exposed to sunlight to prevent rapid chlorine depletion.
   • Unstabilized Chlorines: Suitable for indoor or shaded pools, and for quick shock treatments.
4. Best Practices for Chlorination:
   • Shocking the Pool: Use liquid chlorine or granular Cal Hypo to rapidly increase free chlorine levels for disinfection.
   • Maintenance: After shocking, use stabilized chlorine tablets to maintain consistent chlorine levels over time.
   • Non-Chlorine Shock: Useful for quick sanitization before pool use, especially after heavy rain or before pool parties.
5. Application Tips:
   • Testing: Regularly test chlorine levels 2-3 times a week.
   • Safety: Do not mix different types of chlorine tablets in the same chlorinator or floater to avoid chemical reactions.

This guide provides essential information for pool owners to choose the right chlorine products and maintain a healthy and clean swimming pool.
