Understanding Pool Chemicals

Chemicals are essential for pool sanitation and balance. Get a breakdown of what each chemical does and how to use it correctly.

Common Pool Chemicals & Their Uses

  • Chlorine: The primary sanitizer that kills bacteria and algae.
  • Bromine: A chlorine alternative, often used in spas and indoor pools.
  • Cyanuric Acid (CYA): Also known as stabilizer, it protects chlorine from UV breakdown.
  • Algaecides: Prevent algae growth and keep water clear.
  • Shock Treatments: Boost chlorine levels to eliminate contaminants.
  • Muriatic Acid & pH Reducers: Used to lower pH and alkalinity.
  • Baking Soda & Alkalinity Increasers: Help stabilize pH levels.

How to Handle Pool Chemicals Safely

  • Store in a cool, dry place, away from direct sunlight.
  • Never mix different chemicals together—they can react dangerously.
  • Always add chemicals to water, not the other way around.
  • Use protective gear like gloves and safety glasses when handling strong chemicals.

Signs You Need to Adjust Your Pool Chemicals

  • Strong chlorine smell? May indicate chloramine buildup—shock the pool.
  • Cloudy water? Could be a high pH or calcium imbalance.
  • Green water? Algae is present—adjust chlorine levels and brush surfaces.
  • Itchy skin or red eyes? Likely due to unbalanced pH or high chloramine levels.
