Fluoride, Arsenic V and pre oxidized Arsenic III, Other residual heavy metal ions. FLUORIDE: Testing for fluoride was once based on 20-30ppm of the ion in the influent aqueous solution at a waft rate of not more than 3 gpm per cubic foot of media. Results of < 1ppm of the fluoride ion in the effluent were typical for the media (95% reduction). Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved (99.75% reduction). ARSENIC: This product uniquely targets all the family of arsenic oxide anions in addition to the arsenic cations. REPLACEMENT: Under normal conditions it's endorsed that each set of two PF-2 elements be replaced after 1,000 gallons.
