Chlorine Demand Problems

Chlorine demand occurs when your pool consumes chlorine faster than normal, often 5-10 times the usual rate. The pool literally 'eats' chlorine as fast as you add it, leaving no residual to sanitize the water. This happens when contaminants like algae, organic debris, or nitrogen compounds overwhelm the chlorine's oxidizing capacity.

Excessive chlorine consumption is caused by: invisible algae growth (most common), high organic load from debris or bather waste, nitrogen compounds forming chloramines, biofilm on pool surfaces, or following periods of neglect. In Southlake, Westlake, Grapevine area, dust storms and pollen can introduce massive organic loads that create chlorine demand overnight.

Breaking chlorine demand requires 'breakpoint chlorination': Calculate 10 times your combined chlorine level (or 20-30 ppm for severe cases), add calcium hypochlorite or liquid chlorine all at once after dark, run pump continuously for 24-48 hours, brush all surfaces vigorously, and clean filters thoroughly. The pool will be unsafe for swimming until chlorine drops below 5 ppm.

For chlorine demand, you need 5-10 pounds of calcium hypochlorite per 10,000 gallons, far more than normal shocking. Standard shock is 1 pound per 10,000 gallons, but demand requires 10-30 ppm free chlorine to break. This extreme level is necessary to oxidize all contaminants at once.

Yes, chlorine demand is dangerous because it means your pool has no effective sanitizer. Without adequate chlorine, bacteria, viruses, and parasites can multiply rapidly. The pool is unsafe for swimming until demand is broken and 1-3 ppm free chlorine is maintained. Additionally, the high chlorine levels needed for treatment are hazardous.

No, never swim in a pool with chlorine demand. The lack of sanitizer makes the water unsafe, potentially harboring dangerous pathogens. During treatment, extreme chlorine levels (10-30+ ppm) make swimming dangerous. Wait until chlorine stabilizes at 1-5 ppm before swimming, typically 24-48 hours after successful treatment.

Recurring chlorine demand indicates underlying issues: persistent algae problems (check for phosphates), inadequate filtration or circulation, biofilm harboring contaminants, or continued introduction of organics. CoOpPools technicians can identify root causes and implement preventive measures to stop the cycle.

DIY treatment costs $150-300 for chemicals (25 lbs shock plus algaecide), but may require multiple attempts. Professional treatment by CoOpPools runs $200-400 including diagnosis, proper chemical application, monitoring, and filter cleaning. Our worker-owned technicians ensure it's done right the first time, often saving money overall.

Breaking chlorine demand typically takes 24-48 hours of continuous filtration after shock treatment. Severe cases may require 3-5 days with multiple treatments. You'll know it's broken when chlorine holds steady at the level you add it. Professional service can often break demand faster with commercial-strength products.

Chlorine demand means chlorine is being consumed by contaminants. Chlorine lock means chlorine is present but ineffective due to extremely high cyanuric acid (CYA) levels. Demand shows 0 ppm free chlorine readings; lock shows normal readings but no sanitizing effect. Both require different treatments - demand needs shocking, lock needs dilution.
