Why Every Swimming Pool Needs 90% Chlorine?
Chlorine 90% is an essential primary sanitizer for every swimming pool, regardless of whether it uses a salt system, mineral system, ionizer, ozone, UV, or other health-oriented treatment systems. These systems function as secondary sanitizers and cannot kill bacteria as rapidly as chlorine. If the water becomes cloudy, develops an odor, or experiences heavy usage, chlorine should be added immediately to restore water quality. Maintain a minimum chlorine level of 0.5 ppm to protect swimmers from newly introduced contaminants. Keeping chlorine in stock ensures your pool remains safe at all times. Store chlorine in a dry area, tightly sealed, and away from moisture. If you need guidance on dosage or product selection, feel free to ask anytime.
