Partly due to my prodding starting in October 2010, the EPA has just changed the registration on PristineBlue® as of 03-May-2012 so that they cannot call themselves a bactericide nor claim to "control bacteria". Now they can only claim “to control algae and nonpublic health bacteria, and bacteria that cause odor problems in residential swimming pools, spas and hot tubs.” The “nonpublic health bacteria” is a reflection of the fact that copper ions alone do not even control (let alone kill) fecal or blood-borne bacteria at the concentrations of copper allowed in pools.
