Crystal Ball for the Bath ~ Questions and Answers


A. The Crystal Ball for the Bath may be used to remove chlorine from hot tubs and spas, but it may take longer or require two plastic balls because of the greater volume of water than a bathtub.
Very Important:
Once you have removed chlorine from a hot tub or spa, you must follow the hot tub or spa manufacturer’s instructions on sanitizing the tubs/spas between uses. If you fail to re-disinfect the tub/spa you could encourage unwanted bacteria or fungus growth.
Q. Are any materials used in the Crystal Ball for the Bath either harmful or toxic?
A. KDF Formula 73 (F-73) is a specially processed alloy of 70% copper and 30% zinc. The filament is processed by special machinery, which produces a fine, hair-like strand of brass only 60 to 80 microns in thickness, about the same as a human hair. Each Crystal Ball for the Bath contains 1 & 1/2oz. of F-73 strands, which if laid end to end would extend over 4000 feet. This provides the Crystal Ball for the Bath with a great surface area, which in turn accelerates the electro-chemical action of the F-73. The Crystal Ball for the Bath is absolutely unique. There is nothing with which to compare it.
