To kill bacteria, viruses, and germs
Sanitizers destroy harmful microorganisms introduced by swimmers, rain, debris, and environmental contaminants.
When the water looks cloudy or dull
Low sanitizer levels allow contaminants to build up, leading to hazy or murky water.
To prevent algae growth
Chlorine stops algae spores from growing before they turn the pool green, yellow, or black.
After heavy pool use or pool parties
Sweat, sunscreen, body oils, and cosmetics consume sanitizer quickly and need to be replenished.
When the pool has a strong “chlorine smell”
This usually means there isn’t enough free chlorine—chloramines have formed and need to be broken down with proper sanitizing.
After rain, wind, or storms
Weather introduces dirt, pollen, leaves, and organic debris that reduce sanitizer effectiveness.
If swimmers experience eye or skin irritation
Poor sanitation and imbalanced chlorine levels can cause discomfort.
When water tests show low or zero sanitizer levels
Consistent testing ensures sanitizer stays within the safe range to protect swimmers.
To maintain safe, swim-ready water at all times
Sanitizers work continuously to keep the pool healthy—not just when problems appear.
