Hi Leslie, this is one of the problems I have had i.e. the machine hasn't turned off for over six hours even though the ambient temperature has actually risen here. The ppm has only been six at this point so to reach 10ppm I've had to run it for another two hours. This is for only half a litre, so I'm wondering if this is what is causing the yellowing. I use a simple TDS meter which is not accurate but is near enough. The red laser pointer is to test the finished CS for 'tyndall effect' which shows that you actually have silver in your solution. If you have, it makes a clear red line through the CS water. dee
