Chlorine is the unsung hero of swimming pools, keeping water safe, clean, and inviting. But what makes it so effective, and why do pools rely on it to maintain hygiene?
How Chlorine Works in Pools
- Disinfectant power: Chlorine forms hypochlorous acid and hypochlorite ions that oxidise and kill bacteria, algae, and other microorganisms.
- Preventing algae growth: Chlorine disrupts algae cells, keeping water clear and safe.
- Cost-effective sanitation: Readily available and easy to control, chlorine is the most practical method for pool sanitation.
💡 Did you know? The strong chlorine smell isn’t always high chlorine—it’s often chloramines, compounds formed when chlorine reacts with organic matter like sweat or urine. High chloramine levels indicate a lack of free chlorine and can irritate skin and eyes.
Why Chlorine Levels Matter
- Too low (<1 ppm): Water quality decreases, bacteria can thrive.
- Optimal (1–3 ppm): Water is safe, algae-free, and comfortable for swimmers.
- Too high (>3 ppm): Can cause skin and eye irritation.
