Card on Guard - Chlorine Alternative

Item #103031


SHIPS TODAY if ordered in the next:

Card On Guard features their BioPhotonX™ UV Light Conversion Technology, to capture and magnify UV lights to break down portions of the water molecules that reform to create free radicals that may attack.


  • Saves you money
  • Less maintenance
  • Healthier bathing
  • More natural and enjoyable water
  • Better for the environment

How to use:

  1. Place Card On Guard in your pool or hot tub after testing pool/hot tub to ensure chlorine/bromine is at 2 ppm
  2. The next time you would put chlorine, bromine or other sanitizing chemicals into your water, reduce the amount you use by 50% (i.e. if normally using 4 ozs of chlorine, reduce to 2 ozs; if 2 tablets normally used, reduce to 1 tablet)
  3. On your next regular water quality check, if free chlorine or equivalent quality measure is in the acceptable range (1-2 ppm for chlorine/bromine), reduce the quantity of chlorine (or other chemicals) by another 50% (i.e. if 4 ozs originally used and initially reduced to 2 ozs, then reduce to 1 oz)
  4. Decrease or increase the amount of chlorine/bromine you add based on free chlorine/bromine level readings of weekly water tests
