High Combined Chlorine

Combined chlorine (chloramines) forms when free chlorine binds with nitrogen compounds from sweat, urine, body oils, and cosmetics. Unlike free chlorine, chloramines are weak sanitizers that create the strong 'chlorine smell' and cause eye/skin irritation. Combined chlorine above 0.5 ppm indicates contaminated water needing treatment.

Strong chlorine smell actually indicates chloramines (combined chlorine), not too much chlorine. Chloramines form when there's insufficient free chlorine to oxidize contaminants from swimmers. Clean pools with adequate free chlorine have little to no smell. The solution is more chlorine (breakpoint chlorination), not less.

Eliminate chloramines through breakpoint chlorination: Test combined chlorine level using DPD kit, shock with 10 times the combined chlorine reading (1 ppm combined = 10 ppm shock), use cal-hypo or liquid chlorine only, run pump continuously 24-48 hours, don't swim until chlorine drops below 5 ppm. This breaks chloramine bonds permanently.

High combined chlorine results from: heavy bather loads introducing sweat and oils, inadequate pre-swim showering, pet contamination, fertilizer runoff with ammonia, insufficient free chlorine to oxidize contaminants, and poor circulation allowing organics to accumulate. Even well-behaved swimmers produce ammonia naturally.

High combined chlorine poses health risks: chloramines are respiratory irritants, cause severe eye and skin irritation, trigger asthma attacks in sensitive individuals, indicate inadequate sanitation (bacteria/virus risk), and create an unpleasant swimming experience. WHO recommends keeping combined chlorine below 0.2 ppm for safety.

Test combined chlorine using DPD test kit (not basic strips): Test free chlorine first, then total chlorine, subtract free from total to get combined chlorine (Total - Free = Combined). Problem level is above 0.5 ppm. Test strips cannot accurately measure combined chlorine. Professional testing recommended for accuracy.

Breakpoint chlorination is adding 10 times the combined chlorine level in shock to break chloramine bonds. For example, 1 ppm combined chlorine requires 10 ppm shock dose. This oxidizes chloramines back to free chlorine and nitrogen gas, eliminating smell and irritation. Pool is unsafe until chlorine drops below 5 ppm.

Swimming with combined chlorine above 0.5 ppm is unpleasant and potentially harmful. Symptoms include: burning eyes and skin, respiratory irritation, strong chemical smell, and possible asthma triggers. While not immediately dangerous, high chloramines indicate poor water quality and inadequate sanitation.

Breakpoint chlorination typically takes 24-48 hours: Initial reaction occurs within hours, but chlorine levels remain dangerously high for 1-2 days. Pool is unsafe for swimming until free chlorine drops below 5 ppm. Keep pump running continuously and test before allowing swimmers back in the water.

Chloramine treatment costs $75-250: DIY with cal-hypo shock ($35-60) plus testing supplies, or professional breakpoint chlorination ($125-250) including proper calculations and safety monitoring. CoOpPools technicians prevent chloramines through proper maintenance, saving the need for expensive shock treatments.
