SILVER IONS QUESTIONS AND ANSWERS
Question: How are the silver ions actually added to the water?
Answer: The silver ion cartridge contains ceramic beads that are infused with silver. By placing the cartridge in the filter standpipe, it is
subjected to the flow of water created by the jet pump’s operation. The flowing water, through a chemical erosion process, carries with
it the silver ions necessary to add a sanitizing residual to the spa water.
Question: What happens if I do not add the weekly non-chlorine oxidizer treatment?
Answer: The contaminants in the water may coat the silver ion cartridge’s ceramic beads, blocking the silver ions’ release into the
water. When this occurs, there will be no residual of silver ions present in the water, eliminating them from the sanitizing process.
Question: How often should the FreshWater Ag + ® silver ion purifier cartridge be replaced?
Answer: The cartridge must be replaced every four months. Please refer to the instructions provided with each FreshWater Ag + silver
ion purifier cartridge.
Question: Why can’t I use bromine or biguanides instead of MPS or chlorine?
Answer: Bromine and biguanides will chemically react with the sanitizing action of the silver ions. This will eliminate their beneficial
sanitizing effect.
DOS AND DON’TS
• DO check your MPS or Sodium Dichlor chemical level prior to each use.
• DO change the FreshWater Ag + silver ion purifier every 4 months.
• DO test Total Alkalinity and pH weekly.
• DO use MPS for spas only, such as Hot Spring ® MPS non-chlorine oxidizer .
• DO store all chemicals in a tightly sealed container in a cool, dry place.
• DO check your sanitizer prior to each use.
• DON’T use bromine, sodium bromide or biguanides. These are an active sanitizer and will combine with the silver ions to
inactivate them.
• DON’T use a water clarifier. Clarifiers will cause the spa water to become cloudy.
