It is primarily an oxidizer and will only increase water clarity.  It will not sanitize the water. It is not a stand alone sanitation device.  It must be used along with your regular sanitizer. Contact Watkins Manufacturing if you have any questions concerning water chemistry.The insert may become clogged from time to time. It will need to be unclogged or replaced. The jet should spray a shower of bubbles to center of the spa.
