Click on the box "pair of silver wires" to select the silver wire gauge and view pricing. THE EZ-2 HAS A 1 YEAR REPAIR/REPLACEMENT GUARANTEE AGAINST DEFECTS IN MATERIALS OR ASSEMBLY AND COMES WITH FREE UNLIMITED TECHNICAL SUPPORT. The EZ-2 Barebones makes both clear and yellow cs, depending on the time period the unit is operated. 5 ppm to 10 ppm are clear, 15 ppm is faint yellow and 20 ppm is yellow/amber. Above 20 ppm the cs is orange to reddish brown. The photo is 15 ppm. This is due to the range of particle sizes. The smallest silver particles are produced at 5 ppm to 10 ppm and larger silver particles, which reflect yellow/orange/red light, are made as the concentration increases. The two 6-inch 14 gauge 9999 pure silver wires will make about 75 gallons of 15 ppm colloidal silver. All gauges of replacement silver wire are available fro LifForce Devices on Ebay.
