DIRECTIONS: Each fluid ounce of SpaSILVER treats up to 20 gallons of fresh water to help keep a clean hot tub / spa bacteria, algae, fungus, and odor free – to keep the already clean hot tub / spa water fresh for a longer period of time than if untreated with SpaSILVER. Add addition bottles as necessary. At the first sign of biological growth, or every 90 days, drain & clean hot tub / spa and retreat fresh added water as directed above.
WARNING: Do not come in contact with SpaSILVER if allergic to Silver. Do not allow SpaSILVER to freeze solid or the colloidal suspension of Silver nanoparticles will collapse and the product will be ruined. Please do not have SpaSILVER delivered to an outside mailbox or front porch or other location in freezing conditions.
NOTE: Many Silver water treatment products are sold as “colloidal Silver”, but are not “colloidal Silver” at all as the Silver exists as ions dissolved in water rather than as bio-available nanoparticles colloidally suspended in water; additionally, far too many ionic Silver products are not just the Silver ions in water, but are actually dissolved dangerous Silver salts such as Silver Nitrate or Silver Nitrite. The telltale sign of a quality ionic Silver product is a clear appearance (no color) that does not test positive for molecules like Nitrate, Nitrite, etc. The telltale sign of a dangerous ionic Silver product (even if sold as “colloidal Silver”) is a high claimed concentration far in excess of 200 ppm. Those must be tested and the consumer will see these are just cheap dangerous dissolved Silver salts being sold as “colloidal Silver” or even as ionic Silver solutions. SpaSILVER is not ionic Silver, so it is not clear in color and not an issue as there are absolutely no Silver salts in SpaSILVER. In addition to the purity of the Silver and the bio-availability (nanoparticle size), please consider these issues as well when discerning which true colloidal Silver water treatment to purchase and use to keep your hot tub or spa water fresher longer.
