DESCRIPTION:  SpaSILVER™ Water Booster diatomic Silver nanoparticle AgNP water treatment additive for your hot tub or spa was engineered for the health of your skin and mucous membrane surfaces by supplying a key water treatment additive, Silver, to inhibit pathogens and prolong the freshness of water between cleaning and refilling your hot tub or spa. SpaSILVER™ Water Booster true colloidal Silver hot tub / spa water treatment additive consists of 99.99+% pure Silver nanoparticles (AgNPs) colloidally suspended and dispersed in pure water. SpaSILVER is a very dark blackish brown colored liquid when seen from the front and has a orange color when backlit, but will not change the color of the water in your hot tub or spa and will not stain your hot tub or spa; the AgNPs in SpaSILVER are diatomic (just 2 Silver atoms in size  - only 0.6 nm). SpaSILVER is odorless, non-irritating, and not photo-sensitive. SpaSILVER is non-toxic, has a safe dosage of one fluid ounce of SpaSILVER for each 25 gallons of fresh water to be treated, and is safe to use in perpetuity to preserve fresh, clean water so that it remains fresh in between routine cleanings. The AgNPs in SpaSILVER are elemental, non-ionic, non-reactive, and are just a two Silver atoms (diatomic) in size and 100% bioavailable. Each cup of SpaSILVER treats 200 gallons of fresh, clean water; this 1 gallon jug treats and preserves over 3,200 gallons of fresh, clean water. SpaSILVER does not require refrigeration after opening and has an infinite shelf life if stored at room temperature.

This is 500mL (16.9 Fl Oz) of SpaSILVER™ Water Booster - Diatomic Silver NanoParticle AgNP Hot Tub / Spa Water Treatment Additive in a blue BPA-free plastic bottle - triple sealed for your protection. 

DIRECTIONS: Add one fluid ounce (1 Fl Oz) of SpaSILVER™ to your hot tub or spa for every 25 gallons of capacity it is rated for to help keep the newly added, fresh clean water to your clean hot tub / spa bacteria, yeast, algae, fungus, and odor free. Add additional amounts as necessary, at the first sign of biological growth, or every 90 days. Then, drain & clean your hot tub / spa, and retreat the freshly added clean water as directed above. Unopened containers of SpaSILVER have an extended shelf life if stored at room temperature.

NOTE: Providing your spa or hot tub with AgNPs by using SpaSILVER™ Water Booster diatomic Silver nanoparticle AgNP water treatment additive every 90 days to the new fresh water in your newly cleaned spa or hot tub will likely keep the water fresh between changeouts, but indoor spas and hot tubs fair better than outdoor where they are exposed to many more variables. Do not add SpaSILVER to dirty spa or hot tub water and expect miracles. SpaSILVER is a preventative water treatment additive, not pool shock. 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 Silver nanoparticles (AgNPs) colloidally suspended and dispersed 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.  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 which will not change the color of your water or stain your hot tub or spa. 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.

CAUTION: If allergic to Silver, please consult a physician before using (preferably a naturopathic physician and not an allopathic corporate controlled physician).Protect from freezing; if SpaSILVER is allowed to freeze solid, the colloidal suspension of Silver nanoparticles (AgNPs) will collapse and, once thawed, will fall to the bottom of the container and appear as fine black dust as all color disappears from the liquid and it is clear (just water). For this reason, do not have your purchase shipped to an outside location in potentially freezing conditions. Once received, just store SpaSILVER at room temperature.
