Shock Treatment is a disinfection process necessary when a water system has been contaminated by pathogenic and nonpathogenic microorganisms, caused by a presence of decayed material, animal or human waste, and other contaminants.
Shock Treatment involves incorporating of chlorine to pool water in amounts that are larger than the standard amounts. Shock treating is highly essential as it protects you and your family from bacteria and other organic or inorganic contaminants.
A shock treatment adds 5-10 ppm FAC (Free Available Chlorine). This concentration amount is ideal for preventing and counteracting common pool water problems. The pump and filter must be in operation as the pool water undergoes the treatment. After the process, the FAC level must be 1-4 ppm before entering the pool.
NOTE: For best results, always adjust pH to 7.2 to 7.6 before shock treatment.
When Should You Shock Treat?
An additional shock treatment should be given when any of the following situations occur:
Extreme weather conditions
Severe sun exposure
Swimmers complain of eye irritation
Appearance of algae
Cloudiness in water
