FreshWaterAg+ silver ion purifier introduces silver ions into the spa water, inhibiting bacteria growth. When combined with MPS, or chlorine,
oxidizes particulates in the spa water.
It is important to follow the recommended application and maintenance programs outlined for each product’s use.
If the spa is being used over an extended period of time, such as a whole afternoon or evening, additional sanitizer will be needed.
A weekly “shock treatment” is required.
The shock treatment quickly destroys any remaining contaminants while revitalizing the silver ion cartridge, allowing the silver ions to continue to
be released into the water. Without this weekly shock treatment, the silver ion cartridge may stop releasing silver ions into the water.
To weekly “shock treat” your spa you may use either MPS or sodium dichlor. It will require much less sodium dichlor to administer the shock
treatment than MPS (one teaspoon of sodium dichlor has oxidizing capabilities comparable to two tablespoons of MPS). Sodium dichlor may be a
more appropriate weekly shock for those users that experience heavy bather load conditions.
IMPORTANT NOTE: MPS is an oxidizer, not a sanitizer
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 circulation pump filter
standpipe, it is subjected to the continuous flow of water created by the pump’s 24 hour circulation. 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 shock 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 FreshWaterAg+ silver ion purifier cartridge be replaced?
Answer: The cartridge must be replaced every four months. Please refer to the instructions provided with each FreshWaterAg+ silver ion purifier
cartridge.
Question: Can I use the FreshWater
® III ozone system in addition to the silver ion system?
Answer: Yes. In fact, it is preferred! The use of the FreshWater III ozone system will enhance the performance of the silver ions and may
substantially reduce the need for supplemental chemical treatments when the spa is not in use.
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 dichlor chemical level prior to each use.
• DO shock the spa weekly (use either MPS or sodium dichlor).
• DO change the FreshWaterAg+ silver ion purifier every four months.
• DO test Total Alkalinity and pH weekly.
• DO use MPS for spas only, such as Hot Spring® MPS chlorine-free oxidizer.
• DO store all chemicals in a tightly sealed container in a cool, dry place.
• 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.
