The Freshwater Ag+ Continuous Silver Ion Cleaner is designed for easy replacement within your compatible hot tub system. Refer to your hot tub's owner's manual for specific instructions on locating and replacing the existing silver ion cartridge or filter.
The Hot Spring Freshwater Ag+ Continuous Silver Ion Cleaner operates continuously once installed. It works by releasing silver ions into the spa water, which helps to inhibit the growth of bacteria and maintain water clarity. This product is designed to work in conjunction with your hot tub's filtration and ozone (if applicable) systems.
No daily user interaction is required for the operation of this cleaner beyond ensuring proper water balance and filtration.
The Hot Spring Freshwater Ag+ Continuous Silver Ion Cleaner is designed to be effective for approximately four months under normal spa usage conditions. After this period, the silver ions will be depleted, and the cartridge will need to be replaced to maintain water quality.
If you experience issues with water clarity or quality after installing the Freshwater Ag+ Continuous Silver Ion Cleaner, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Cloudy Water | Depleted cartridge, improper water balance, dirty filters, high bather load. | Replace cartridge if over 4 months old. Test and adjust pH/alkalinity. Clean or replace filters. Shock the spa water. |
| Algae Growth | Cartridge depleted, insufficient sanitizer, poor circulation. | Replace cartridge. Ensure proper sanitizer levels (e.g., chlorine/bromine as supplemental). Check pump and jets. |
| Unusual Odor | Contaminants in water, need for shocking. | Shock the spa water. Ensure proper filtration and water balance. |
For persistent issues, consult a qualified hot tub technician or contact Hot Spring customer support.
