Trem and Richard: Thanks for the replies. I now have a better understanding of what is going on and how to deal with it.
However, I am also pretty sure I made a mistake which contributed to the problem, and I thought I would pass that info on. I noticed on the last batch that I did not fill the water quite high enough so that the stirrer on the SG6 was ALL the way in the water. Only the tip of it was. I now believe that there was some agglomeration at the negative electrode because the water was not being stirred as vigorously as before. I just made another batch, being sure to fill the water to just below the red and black posts. This time, most of the stirrer was in the water. Sure enough, there was very little accumulation. I noticed a tiny amount of white stuff when I removed the electrodes from the water, but it disappeared almost as soon as I saw it, dissolving into the solution, and the solution is perfectly clear with nothing visible on the bottom. SG6 users, take note. Del ----- Original Message ----- From: Trem To: Delmont Neroni Sent: Friday, December 26, 2003 11:47 AM Subject: Beginner's Question Hi Del, That's exactly the way it works. Some of the ions are attracted to the cathode during production and in the process gain an electron which causes them to turn back to elemental silver. That's what you see....not oxide. It is normally so heavy that it falls to the bottom of the vessel and when you decant the CS it stays on the bottom. I do not recommend filtering as it usually causes agglomeration. If the meter reads 9.5, subtracting .6 for the water reading and multiplying by 1.2 will give you close to 11 PPM. Hope this helps you. Best regards, Trem
