Determining the appropriate amount of oxidizing sanitizer to introduce into a 165-gallon spa is critical for maintaining water quality. This process, often referred to as “shocking,” eliminates organic contaminants and sanitizes the water. An example would be adding a specific measured dose of dichlor granules to a spa after heavy use to eliminate chloramines.
Maintaining adequate sanitizer levels is vital to preventing the growth of bacteria and algae, ensuring a safe and enjoyable spa experience. Historically, various methods of water sanitation have been employed, evolving from simple filtration to the use of chemical treatments. The benefit of correctly shocking a spa is clear, sparkling water and minimized risk of infection.
