Excessive Chlorine Loss

The consistent inability to maintain chlorine levels is also called “chlorine demand” and is most often caused by a high level of inorganic and organic contaminants in the water. Those contaminants force the chlorine to work extremely hard to oxidize them, leaving little chlorine to protect swimmers. Proper chlorine levels cannot be re-established without first eliminating the contaminants. External factors such as sunlight and heat also contribute to chlorine loss.

• Take a water sample to your BioGuard Dealer​ to determine the extent of the demand
• Add Pool Complete® 911​ to help remove contaminants
• Add your preferred (chlorine based) BioGuard Shock​ to correct sanitizer levels

• Maintain an appropriate sanitizer residual of 1 - 3ppm
• Shock​ routinely or as needed depending on bather load
• Test water frequently and adjust as needed
• Routinely check for circulation and filtration issues
• Add Pool Complete® Weekly​ to your weekly maintenance routine to reduce contaminant levels
