The ancient Phoenicians, Greeks, Romans Egyptians, and others were recorded to have used Silver to preserve water and prolong its freshness. SpaSILVER™ concentrated true colloidal Silver AgNP spa and hot tub water treatment uses Silver as ultra-pure Silver nanoparticles (AgNPs) to preserve clean water and prolong its freshness. FountSILVER concentrated true colloidal Silver AgNP spa and hot tub water treatment has a purity, safety, and effectiveness that the ancient Phoenicians, Greeks, Romans and Egyptians could only dream of (explained below). 

DESCRIPTION: FountSILVER™ concentrated true colloidal Silver AgNP indoor fountain and water feature treatment is non-toxic and consists of 99.99+% pure Silver as 100% bioavailable Silver nanoparticles (AgNPs) colloidally suspended and dispersed in pure deionized water. FountSILVER was engineered by Biochemist Michael Miller (see SAFETY below) as a non-toxic additive to keep new, clean water in your indoor fountain or other water features (such as indoor waterfalls) fresh for longer vs no treatment. This is 1 US Gallon (128 Fl Oz) of FountSILVER™ concentrated true colloidal Silver AgNP indoor fountain and water feature treatment in a white BPA-free plastic jug.

PURITY: The Silver nanoparticles (AgNPs) in FountSILVER™ concentrated true colloidal Silver AgNP indoor fountain and water feature treatment are made from 99.99+% pure Silver - this is much more pure than Sterling (only 92.5% purity) or "pure" Silver which may only be 99% or 99.9 pure (max). Purity is critical as the impurities (the 0.1% to 7.5 %) are harmful to the ecosystem in the fountain - especially the fish and other aquatic fauna. The Silver nanoparticles in FountSILVER™ concentrated true colloidal Silver AgNP indoor fountain and water feature treatment have a purity of 99.99+% at a safe and effective concentration of 250 mL per 200 gallons treated.

SAFETY: FountSILVER™ concentrated true colloidal Silver AgNP indoor fountain and water feature treatment is manufactured, lab tested (to ensure quality and safety), bottled, and inspected in Nutraneering’s FDA registered and audited facility in Irvine, California (USA). Michael Miller is a Biochemist and former NASA scientist at NASA’s LBJ Space Center (Houston), Building 37 (Life Sciences Building) in the Water And Food Analytical Laboratory (W.A.F.A.L) who founded Nutraneering in 2011 and currently serves as the CEO of Nutraneering Incorporated - a California corporation.

EFFECTIVENESS: When it comes to Silver nanoparticles, absorption matters. The AgNPs in FountSILVER™ concentrated true colloidal Silver AgNP indoor fountain and water feature treatment are ultra-pure with the smallest nanoparticle size on the market (see test tube color comparison image included in this listing) which yields the highest surface area and bioavailability. No other true colloidal Silver AgNP water treatment in the marketplace provides higher safety, absorption, and bioavailability than FountSILVER. The AgNPs in FountSILVER are 100% bioavailable.

DIRECTIONS: FountSILVER™ concentrated true colloidal Silver AgNP indoor fountain and water feature treatment is non-toxic and perfectly safe to add to any fountain or water feature - even waterfalls; it will not evaporate away as other treatment products do. Each fluid ounce of FountSILVER™ concentrated true colloidal Silver AgNP indoor fountain and water feature treatment treats up to 23.5 gallons of fresh water to help keep a recirculating fountain or waterfall algae, fungus, and odor free for longer. Add additional bottles as necessary. At the first sign of biological growth or every 90 days, drain and clean the fountain or water feature (such as a waterfall)  and retreat freshly added water as directed above. Unopened, sealed bottles of FountSILVER have a proven shelf life of 15+ years. Once received, just store FountSILVER at room temperature out of direct sunlight. Do not allow FountSILVER to freeze or the colloidal suspension of AgNPs will collapse.

CAUTION: Do not come in contact with FountSILVER if allergic to Silver. 

FREE SHIPPING: Shipping is free within the USA - including AK, HI, and all US territories.

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 free 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. FountSILVER is not ionic Silver, so it is not clear in color and not an issue as there are absolutely no Silver salts in FountSILVER. 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 newly added clean indoor fountain or water feature water fresher for longer.
