Additionally, ozone is the strongest commercially available disinfectant, yet very safe, and over 3000 times faster than chlorine for purifying water and is more effective for elimination of e. coli, giardia, legionnella, and cryptosporidium. A. Ozone is very effective as a sanitizer, however because of the low doses being produced along with ozone's short life span ,it is improbable that there will be a residual of sanitizer in the water, therefore, it is recommended that you maintain a 1 PPM residual of chlorine to prevent typical algae problems. Reduced maintenance time and chemical usage will give you more time to enjoy your pool or spa. A virus is a parasitic, infectious microbe which can cause disease in humans.

Cysts are protozoa that produce a special protective shell.
