Most of you replying are missing the point about starting out with higher voltage. The resistance of pure water is very high so it takes time to get the conduction (amount of silver being released into the water) to increase to the point where the current limit will take over. Having higher voltage at the beginning gets you to the current limiting point much faster. After the current limit circuit is saturated, it reduces the voltage across the electrodes. (It does this by increasing it's resistance and thereby dropping more voltage across itself and leaving less voltage to appear across the electrodes.) So starting with a higher voltage will get your CS batch going faster at the beginning. Best to have a current limit circuit which is sized for the silver electrodes you are using so you can maintain a low current density on the electrodes, as was referred to by Ode. Without a current limit it may be harder to control the reaction at the end of the brew. Dan

I have made about 1 gallon of CS at 15ppm. Is 15ppm OK? Half with 2 batteries and half with 3 batteries and I can tell no difference between the batches. I finally got my 30 volt transformer that I am also going to be using but I am going to use diodes to reduce the milliamps down to around 1.5 or .5milliamps. My question is this..If the milliamps are so low then why do they recommend 27 to 31vdc? I can get the same milliamps using a 6volt 300milliamp transformer as I can with the 30volt 1000milliamp transformer. What am I missing with the voltage issue? Everyone has different voltages they like. Also using two batteries I still have to stir the CS to keep it clear which is not a problem and I also found that if I heat the water to 42 degrees Celsius it doesn't take as long to get 15ppm, so does anyone else heat the water? Also will CS help a person with irritable bowel problems? Now that I switched from Incredimail to Outlook Express my posts might go thru and I thank everyone for their help that they have given me...Cheers..Keithmj <http://i.msgtag.com/aqnpcesnADalgykfcuw/yceqyxfBvimDf.gif> NUDE is not LEWD..Play Naked!!
